Soon after posting that I'm not upgrading from 1.8.10 to 1.8.11 because I don't want to mess anything up I got this when I checked on my forum:
MyBB has experienced an internal error and cannot continue.
Error Type: MyBB Error (42) Error Message: Your board has not yet been upgraded. Please do so before attempting to browse it.
How can I fix this and regain access to my forum without upgrading? I had a web design guy deal with installation and customization and I DO NOT want to undo anything he did with the forum colors and my custom logo and everything!
