I have 3 installs for WordPress Multisite on Hostgator Linux hosting. All three were set up and running fine with this plugin until one of my assistants and/or support from Hostgator moved the wrong wp-config.php files into the wrong installs. The databases and redirects became polluted. I have since fixed this and gone into the databases to correct the erroneous redirects that were created, however the Domain Mapping is missing from the Tools tab of the subdomains. It is in Network as it should be, but not in the subdomains. Doesn't matter whether or not I check the box in settings under Network, all stays the same. Suggestions? Is this in the database or in the config files somewhere?
