I am having the same issue so very interested to know the answer to this.
I have already deleted these folders and removed everything from database tables. However looks like this plugin has totally corrupted our database. I have had problems in the past with plugins, database errors but never been in a situation where nothing will fix this problem. I have been trying for two weeks now with no success, boss is not happy. Looks like our whole company website is lost if we cant access the admin area.
Thank you,
I have run this SQL query and the tables have been moved however I am still getting access denied to wp-admin area. Is there something I could have missed? This has only occured since activating your plugin.
