so this is a dev site that was once up and running and working smoothly, but the hosting company has made a datacenter switch and changed the urls, messing things up really badly.
I've changed the URL to the new one in the wp-config.php file, as well as modified the database to the new home url, but still it can't bring up the site correctly, nor can I log in. When you click "log in" then it just doesn't do anything. No error, nothing.
Any ideas what is wrong and what I can do to fix this?
