I installed this plugin today, and now can't access my blog [ http://marketing.onescrappysite.com/blog ]at all. I get a 500 Internal Server Error . Obviously I did something wrong.
When I first activated the plugin, I was looking at the Manage>Instant Upgrade, reading through the options/directions. I got to the bottom, the "Fed Up with InstantUpgrade?" section. I saw the Change File Modes button, but when I hovered my cursor over it, it didn't seem like an actual button. Like a newb, I clicked to see what would happen. Well, what happened was my blog broke. I guess now I don't have owner rights to the files or something? I checked the folders via ftp, and Owner is set to Read-Write-Execute; Group and All Users are set to Read-Execute.
I backed up the blog before activating the plugin, fortunately. So I followed the directions at http://www.tamba2.org.uk/wordpress/restore/. The sql database was successfully reimported/reinstalled - I can see it in mySql and via FTP. But I'm still getting the 500 Internal Server Error.
Obviously I'm in a bit over my head here, and shouldn't have messed around with something I didn't know for sure what it did.
