My friend decide to add 2nd WP but I already installed WP in root directory while ago. I guess I mess it up when I tried to add new sub-directory name thru admin options.
Now, I cannot get back into admin again - it kept getting error because I put new directory in it. I still can see wordpress but all theme is gone, I guess because it went to new sub-directory.
I haven't upgrade to 2.12 but I can do it if it will help.
How do I undo it or quick fix around it?
