You can't play peekaboo with it. It's not going to get you anywhere. Trust me on this. You have 2 things to try:
1) Admin Panel --> Configuration --> Settings --> General Configuration --> Disable All Plugins ^ try this first. You can turn turn the "disabler" off and enable ALL plugins at once again, at least - if the plugins are not the problem.
2) I am STILL going with an .htaccess issue. A plugin generally will not do this. I don't know how CloudFare is setup but if I had to take a guess it's through the .htaccess for the redirections, unless it just does everything through the DNS. Just try remove it out of the home directory for now. You don't have to delete it. But at the same time, if CloudFag does operate off of the .htaccess, you might have to change your DNS settings regardless.
When I was freelancing a few years back I was working on a Business Improvement Districts website in my area. That was her first issue. It took me forever to figure it out, but I was shocked to shit when I did. The .htaccess has the capability of altering the ENTIRE website. It's like placing a meta tag in your header template, where the {$header} function is called, it's going to be displayed.
I just don't see a plugin causing a 500. This is an HTML error. MyBB is in PHP. The templates are in HTML, but all these templates are doing is designing, they are not programming.
When you get a PHP error, it will display EXACTLY the underlying cause, the file name, and the line it's on. When you get an HTML error, you will get default server pages. 404, 403, 500. (Which, by the way, I am still getting 403 messages every time I log in and out on your forum.)
I'm telling you, just try moving the .htaccess off the server for a bit.
