UPDATE: somehow I fixed it. I suspect it had to do with using the reset password .bat in c:\xampp\mysql\ and/or following these steps:

I recently installed ActiveCollab on XAMP and had no problems until quite recently, which I suspect are closely related to a MediaWiki installation on the same box.

Now, when I go to http://IP/activecollab, I get the following error:

"We are sorry, but activeCollab failed to connect to the database. Error report has been sent to the administrator so problem should be resolved soon."

I suspect that this has something to do with a bad MySQL password or something, and I'm hoping someone here might help me figure out how I can either reset the password to something the PHP code knows, or perhaps change something in the PHP code that matches the password expected in MySQL.

Any help would be greatly appreciated!
