We just moved http://www.velvetrope.com/forums/ubbthreads.php to a new server and everything was working just fine. If you take a look at the page now nothing is loading. I checked our settings and everything is ok, I even downloaded the whole site to our testing server and hooked it up to the same database and everything looks good there (http://velvetrope.php.mudbrick.net/forums/ubbthreads.php). The only think I can think is its a setting on our production server. I haven't been able to find any documentation for what we need for it to run so I can't check it against what we have (we have at least PHP5 and MYSQL 5). I checked our error logs and they don't have anything from the forum. Where should I be looking to find whats set wrong for this to work?

I'm thinking that an older version was released to patch some PHP5 errors, but I'm not for certain which version it was introduced. 7.1.1 is pretty ancient...

But, if it worked before, I'd go through and check permissions on the cache and templates/compile directory; both should be 777 and then delete the files within them (and possibly run the "Clear Cache" script from the control panel.

This turned out to be a corrupt table.
