I'm hoping somebody can help me out. My forum has been working perfectly for quite a while, but just recently the left and right columns quit showing up.

I tried to play with the settings in the control panel, and after updating, my config file had been rewritten with a blank file.

Luckily, I had a backup.
So, now, any changes to the control panel result in a blank config file and a broken forum. And, i have blank left and right columns in my forum. The main body content of my forum still works fine.

Any ideas about what could be causing this?

Thank you,
Evan
