Changing Wordpress Multisite Folder Name

I'm currently having an issue where I have a Wordpress Multisite install however when I changed the folder name in cPanel and then changed the site path in the WP Config, I keep getting a "Cannot Connect to Database" error even though the database information is completely the same.

I tried changing the site path in phpMyAdmin in the WP Options and Metadata tables - but even with that I cannot figure out why I'm getting the error.

Any assistance is very much appreciated.
