问题
Had XAMPP configured and running properly, was able to access phpmyadmin and execute php code on the local server. This morning after starting XAMPP and starting Apache, I get a message saying: "module 'mysqli' already loaded."
I can't log into phpmyadmin- I see the login page, but when I click "go" I simply get a blank page. I was practicing submitting forms into a DB, everything was working fine, now after submitting the form a message comes back: "connect failed with: (2002) A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. "
The XAMPP status page shows everything as being activated. I don't remember making any config changes or doing anything else that could have caused this.
Appreciate any input.

I fixed this by editing my php.ini and commenting these lines back out:
;extension=php_mysqli_mysqlnd.dll
;extension=php_mysqli_libmysql.dll
and typing in this line in their place:
extension=php_mysqli.dll
Worked perfectly.
