You mean change back from 'mysql.x10hosting.com' to 'localhost'?
On your site will be numerous files all ending in .php - if there are only .html or .htm you're not using MySQL. You should have a local copy of your site.
Presuming that there are, you need to search through them using a text editor. Everywhere you see something that looks like this: -
mysql_connect("mysql.x10hosting.com"
replace it with
mysql_connect("localhost"
Just copy 'mysql.x10hosting.com' and 'localhost' (without the speechmarks) paste these into the 'find and replace' function of the text editor, find the first instance, go 'replace' for every instance in every file where you see 'mysql_connect('.
Try and find a code editor like PFE32 to do this in instead of Word or another word processor. These are TEXT files.
There's lots of other ways of doing this, there may be a configuration tool for whatever software you're using, but this is a generic method that most people can cope with.
Upload the modified files to the appropriate directory on the server. You still have to wait 'till everything's fixed.
