Ok, I installed the plug in in the hopes of running the plug in "Add Clone Sites for WPMU (batch)"
I realize now that my set up was all wrong and I get the error:
The domain mapping plugin only works if the site is installed in /. This is a limitation of how virtual servers work and is very difficult to work around.
I am sensing that I am out of my depth here and would like to just remove the whole thing, but I'm having trouble. I removed the sunrise.php file and I eliminated the line from the wp-config.php file and I deleted the plug in.
I am still unable to log in to the admin dashboard. Any assistance would be GREAT.
