The websites connected to counter-wordpress.com. The script/malware had the abbility to enter your database, create a database dump, play sounds (?), get your WordPress password and more.. With the curl_setopt function there were able to install php scripts on your server.
So for those who have problems, a quick guide to fix this. And for those who doesn’t have problems yet. Update TimThumb (latest version here)!

Fix this malware warning step by step:

• Remove code from your wp-config.php or upload a clean version.
  • Inspect your wp-confip.php. They add like 3000 of empty Lines. Somewhere in the middle there is the malicious code. Delete it!
• Delete the files the injected with the curl_setopt function:
  • wp-admin/upd.php
  • wp-content/upd.php
• Some WordPress users (I didn’t) found a ‘temp’ folder in there current theme folder with a file like eab9c5e9815adc4c40a6557495eed6d3.php, or something like that. Delete it.
• Update your WordPress if possible!
• Replace the following file with original files from a clean WordPress installation:
  • wp-settings.php
  • wp-includes/js/jquery/jquery.js
  • wp-includes/js /l10n.js
  • * If you have problems overwriting them, delete them first (on your FTP) and then upload the new file
• Replace timthumb with the latest version
• Change your FTP password
• Change your DB password and change it in wp-config.php
• If Google is warning your visitors (right above the result description in the SERP). Login to webmastertools and ask for a review. It should be gone in 24 hours
• To be sure check your website with these tools:
  • Download the Sucuri WP Check, and follow the ‘how to use’ steps on theyre website
  • Check your site on with a security scanner
• You’re done!

Hopefully your site will be clean after your followed the steps above. Did you found other suspisious thing please let me know by writing a comment.

On a normal WordPress installation you can change the language in your wp-config.php file. When I like to change the language to Dutch (by example) I define:

define ('WPLANG', 'nl_NL');

Make sure the language files (.mo) are located in your languages folder in wp-content.

But I recently tried this on a multisite, and nothing happened!

I discovered that the multisite also stores the language in his settings (database), so you have to change this for every site in your network (it makes sense!).

• In wp-admin go to the site admin area (right top of the admin)
  /wp-admin/network/sites.php
• Chose ‘edit’ for the website(s) you like to change the language
• Go to the settings tab and look for the setting called WPLANG
• Change (or define if it is empty) the language to nl_NL (or your own language)

Website language should be changed now! Again; make sure the language files (.mo) are located in your languages folder in wp-content.

I usually only show the parent pages without children (on a homepage). In the function I use depth=1 to only sum up the top level pages:

wp_list_pages('title_li=&depth=1' );

When visiting a page i like to sum up the subpages of the parent page in a submenu. Sometimes (when using a submenu on a left sidebar) i like to show the parent page again on the top of the subitems. I created a function for this which you can put in your functions.php template file. This function is only created to list 1 level of subpages, no sub-sub is supported (yet) on the moment. Maybe I will update the function when I need it myself

The function in you functions.php looks like this

function wp_list_subpages($list_parent_page = true){	
	global $post;
	$parent_id  = $post->post_parent;
	$parent_link = array();
 
	// if we are on a subpage
	if ($parent_id) {
		while ($parent_id) {
			$page = get_page($parent_id);
			$parent_link[] = '<li><a href="'.get_permalink($page->ID).'" title="'.get_the_title($page->ID).'">'.get_the_title($page->ID).'</a></li>';
			$parent_id = $page->ID; // the parent id we need to list subpages from
			break; // stop after 1
		}
	// if we are on the parent page
	} else {
		$parent_id = $post->ID; // the parent id we need to list subpages from
		$parent_link[] = '<li class="current_page_item"><a href="'.get_permalink($page->ID).'" title="'.get_the_title($page->ID).'">'.get_the_title($page->ID).'</a></li>';
	}
	// default = true
	if($list_parent_page == true){
		echo $parent_link[0];
	}
 
	// list the subpages
	$subpages = wp_list_pages('title_li=&depth=1&echo=0&child_of=' . $parent_id);
 	if ($subpages) { 
		echo $subpages;
 	} 
}

On your template you can use the following function to show subpages (including the parent page):

wp_list_subpages();

If you don’t want to list the parent before the subpages, use:

wp_list_subpages(false);

All comments or improvents are welcome! This is just something i really use a lot and hopefully someone is happy with it.

Based on this piece of code (thanks Robert) I created a hook you can put in your functions.php template file. So the generated page list will get first and last classes, good luck!

/* last and first classes on wp_list_pages */
function wp_list_pages_firstlast($pageList) {
 
	$pageList = preg_replace('/class="/','class="first ', $pageList, 1);
 
	$reversedString = strrev($pageList);
	$reversedSearch = '/'.strrev('class="').'/';
	$endClass = strrev('class="last ');
 
	$pageList = strrev(preg_replace($reversedSearch,$endClass, $reversedString, 1));
 
	return $pageList;
}
add_filter('wp_list_pages', 'wp_list_pages_firstlast');

Then TimThumb was scaling up my small images!

I searched for a couple of hours for a fix but no good results. The only interesting result I found was about the same issue I had (over here). In the issue they refered to an older version of TimThumb which is located here (#69). Well with that version i was capable of fixing my upscaling problem.

The upscaling fix

On line 119 of the current TimThumb you will find:

// generate new w/h if not provided
if ($new_width && !$new_height) {
    $new_height = floor ($height * ($new_width / $width));
} else if ($new_height && !$new_width) {
    $new_width = floor ($width * ($new_height / $height));
}

I replaced that piece with the older part:

// don't allow new width or height to be greater than the original
if( $new_width > $width ) {
    $new_width = $width;
}
if( $new_height > $height ) {
    $new_height = $height;
}
 
// generate new w/h if not provided
if( $new_width && !$new_height ) {        
    $new_height = $height * ( $new_width / $width );        
} elseif($new_height && !$new_width) {        
    $new_width = $width * ( $new_height / $height );        
} elseif(!$new_width && !$new_height) {        
    $new_width = $width;
    $new_height = $height;        
}

Well this worked for me! TimThumb works with my WordPress Multisite and TimThumb isn’t scaling up my small images any more. I’m not a real PHP developer (just a frontend-guy) so maybe this fix is not the best but I hope other people can use it.

If someone knows a better fix or can explain me what is going wrong exactly please leave a comment!

<?php 
   query_posts('orderby=rand'); 
?>

I could be a plugin (like WP Sticky or in my case an other plugin) which is causing the problem. You can try to find and disable the plugin but a more easy solution is this:

Remove the filter before running the query:

<?php 
   remove_all_filters('posts_orderby');
   query_posts('orderby=rand'); 
?>

But watch out, the plugin which is causing the problem doesn’t adds the filter for fun, so you can wreck a plugin functionality with this solution, but it’s fast and easy

Update: This fix is now included in the new version of Verve Meta Boxes!

But I also had this problem with Verve Meta Boxes. I didn’t generate thumbnails within my multi site installation. That’s because Verve is using Timthumb too.

Based on the solution by Binarymoon I managed to fix the Verve timthumb problem to by editing the plugin.

I’m using Verve meta boxes 1.2.6

On line 435 of verve-meta-boxes.php you will find the following code:

echo '<div><img src="'.plugins_url().'/verve-meta-boxes/tools/timthumb.php?src='.$meta_box_value.'&w=180&zc=1&q=95" alt="" />';

Change this to:

$theImageSrc = $meta_box_value;
global $blog_id;
if (isset($blog_id) && $blog_id > 0) {
$imageParts = explode('/files/', $theImageSrc);
    if (isset($imageParts[1])) {
        $theImageSrc = '/blogs.dir/' . $blog_id . '/files/' . $imageParts[1];
    }
}
echo '<div class="verve-img"><img src="'.plugins_url().'/verve-meta-boxes/tools/timthumb.php?src='.$theImageSrc.'&w=180&zc=1&q=95" alt="" />';

And your Verve meta boxes will generate thumbnails again within your WordPress multi site!

Update: This fix is now included in the new version of Verve Meta Boxes!

• More Fields – You can create more (meta) fields with this plugin for post, pages or custom posts. It’s easy and very user friendly. There are plenty of fields to chose from, but no image upload field.. well that’s why i developed Multiple Template Images. You could also look at Verve Meta Boxes. It has a image field but it’s not as user friendly like More Fields.
• Custom Post type UI – You could also define your custom post types true your functions.php. But this plugin comes with a real easy admin interface to create custom post types. You could also try More Types (from the same developers of More Fields).
• Gravity Forms – I’m really glad that I bought the developers license for Gravity Forms. This is much better then Contact Form 7 (which i wrote about in my last top 5). It comes with a very easy form wizzard with all options and types of form fields you like. But the best feature: it saves the entries posted by visitors in your WP admin.
• WordPress SEO – Just released a month ago, it’s good and has every SEO option in it. A nice feature: it comes with a very nice Google snippet preview.
• Simple Page Ordering – This makes page ordening really easy. No extra menu’s or options, it just let you drag and drop your pages or posts in your existing page/post overviews. It has some small bugs but it’s the best attempt so far.

Did I not mentioned a very good plugin? Please let me know by writing a comment.
