THE CAUSE FOUND!!!

I found the cause of this issue. So obvious. Everyone who’s having this issue please follow this instruction!!

DON’T REINSTALL THE WORDPRESS OR BUDDYPRESS. You should just follow the steps below.

1. go to siteurl/wp-admin

2. go to setting -> permalinks

3. Change common settings EXCEPT DEFAULT. If you set it as default, the issue occurs.

If this doesn’t work, please reply.

Thank you all!

Thank you all. I solved this problem. I don’t know what’s the cause though.

I just reinstalled whole WordPress MU & BuddyPress. But I didn’t erased the MySQL DB. So I could use whole data base again normally.

If someone is struggling with this issue, Just reinstall them. It’s easiest way I think.

Thank you Brian!

So you solved the problem by reinstalling WordPress MU and Buddypress right? Did you reset the DB also?
