I recently moved my WordPress Multisite to a new domain but now I cannot get it working. I did a database dump from the functioning multisite, and imported that into a new MySQL database on the same server. I changed my wp-config.php file to reflect the new items and then used this search and replace tool to change all of the old domain names to the new one. The Multisite feature refuses to work and the only way I can even bring up my homepage is to comment out all of the multisite code in the wp-config file. Otherwise, I get an "Error establishing database connection" when I try to load anything. Does anyone have any idea what I might be doing wrong?
