Hi K2eric, My client also is experiencing errors with the plugin after the very latest upgrade. Beforehand, it was working fine and then after 2.1.2 we started getting pop-up error messages about a script not working, anytime we try to visit or do something in the admin.
I tried uninstalling the plugin from WordPress and reupload/install the fresh package, and the same errors happened - and I noticed my custom settings were still in tact. Maybe the old files are not deleting all the way? Is there any other file besides the plugin folder I should be viewing to clear out the settings?
BTW this is when testing on a Mac with Firefox.
