 * hi again
 * I’m getting the following error when uploading an image as a featured image with
   the meteor slides plugin
 * Fatal error: Call-time pass-by-reference has been removed in C:\UniServer\www\
   dash-media\wp-content\plugins\hammy\WPThumb\phpthumb\src\thumb_plugins\backgroundFill.
   php on line 34

 * Hmm, weird one. I’ll ask the WPThumb guys, but likely a plugin conflict.

 * I’ve put a safeguard into the plugin, but would be good if the other plugin did
   the same. Cheers!

 * The issue is that WP Thumb uses call time pass by reference:
 *     ```
       foo( &$var );
       ```
   
 * Which has been removed in PHP 5.4.
 * We’ll fix this in the next version of WP Thumb.
