Version 2.1.3 of the plugin (also tried with 2.1.2)
I recently migrated over from 5 independent blogs to a network. I put all of the images in their appropriate [domain[/wp-content/blods.dir/[id]/files/yyyy/mm] directories and then copied my old DB over to the new one (making sure to replace and change everything to point to the correct locations). Everything is working except thumbnails, they display as the full image instead.
After doing some research I stumbled upon this plugin and am having an issue with regenerating them. Every image gives me this error
"25 of 25" (ID 4797) failed to resize. The error message was: Unknown failure reason.
