Hey guys, I had to enable WP_DEBUG to see what is going on with my thumbnails. The pics are fine when clicked, they display the way they should. The thumbnails, however, are showing up blank. I enclose a couple of screenshots and an error log.
Notice: Undefined index: imgCacheSinglePic in /home/www/algraf-media.cz/www/algraf-media.cz/wp/wp/wp-content/plugins/nextgen-gallery/nggfunctions.php on line 705
