I'm not sure why, but if this extension is enabled, I will not get access to the "Preferences" page under the User's homepage (as in where you can change your password and email address).
What I get is a "Database Error" on the page title, with the contents only displaying: "[4e71f2d9992b54b355af4b8e] 2016-12-26 15:12:39: Fatal exception of type "DBQueryError"". Is there something I need to with the database? The page returns to normal once I disable the extension.
