Hi I just ran your plug-in, after a great review from a friend. I made a back up through your plug-in, as well as a back-up wp tool a developer installed on my site.
I ran your plug-in, and modified some options as suggested—like the name of the wp-content folder, etc. But I DID NOT change the login or admin addresses.
Now, my site is gone...both at the main url and also at /admin or /login.
I can't even get into the CMS.
