I am reverting a Multisite enabled install back to a single install and following the directions outlined here.
Delete any extra sites you may have created. Move the content and users to the main blog or wherever you desire.
Remove the lines we added in the wp-config.php file.
Restore the .htaccess file to the default. One the multisite lines are gone from the config file, you can usually restore these by resaving the permalinks.
Drop these global tables in the database:
I've done all of this and the last step I do is to remove the Multisite lines from wp-config.php
As soon as I do this, I get the dreaded Error Establishing Database Connection.
As soon as I put them back, I'm good to go.
Can someone point me in the right direction as to what I can look for and try?
