 * i have a lot of images on my site, and was moving a bunch around, and deleting
   the original folders.
    the plugin worked like a charm until i tried deleting 
   a folder with another (empty) directory inside it. up came a bunch of blank error
   messages, then a javascript error (sorry, did not record it) before the page 
   came up with “cannot connect to database”.
 * checking the database through my hosting provider gave me a server error (500),
   whilst my other databases opened up fine.
 * I was able to fix it by creating a new database user and password via phpmyadmin&
   updating the credentials in wp-config.php.
 * (just changing the password for the old user allowed me to open the database 
   in phpmyadmin, but going to the website, it took me to the wordpress installation
   screen. i quickly closed that and created the new user – panic, who me? :p )
 * scary, but ultimately no harm done. i shall run a backup before doing any more
   work though 😉
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcannot-connect-to-database-error-fixed%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * I do not know what happened to your database since the plugin uses the WordPress
   core database functions which should not cause any database corruption.
 * Media Library Folder does not allow you to delete a folder if it has any contents.
   This is to prevent accidental deletion of media library files. Next time, try
   deleting the subfolder first.
