No problems here either, I appreciate all your hard work on a wonderful plugin.
Where can I get hold of the development version?
I downgraded previously just by killing the plugin file, uploading a previous version and reinstalling all the .htaccess stuff (which it forced me to do, assuming that I had installed from scratch). All my settings were retained and it worked fine. I may do this again, depending on how quick the bug fix is forthcoming.
I too am having the exact same problem, and disabling this seems to do the trick, however it means that CDN uploading no longer functions. I’ll turn it off for now, then turn in back on when the bug is fixed. I can reproduce it and give my settings if you like.
