Try disabling CloudFare. I as well have been having issues with Chrome and GoDaddy, but it seems to be chrome that is causing the issue and nothing more. I was contemplating getting away from GoDaddy because I thought the server was the issue, but talking to GoDaddy support is like talking to Steven Hawking, so I'm going to pass on that. Besides, I got a pretty good deal for my current hosting package.
In addition to this, have a look at your .htaccess file. See if there's anything unusual in there. I am familiar with this popping up on Wordpress when it goes awry, but I don't think I've experienced it with MyBB.
It's either CloudFare or your .htaccess. Try viewing from a browser other than chrome, and if the problem still persists, you need to have an in-depth look at your .htaccess file. EDIT: P.S. I think it's time for a new partner.. EDIT2: Aside from the above, you seem to have more underlying problems. Login attempts sometimes fail with a 403 error. yourhiddenwebs.ite//403.html Forbidden Multiple Requests Targeted On Server.
I'm still edging towards an .htaccess issue.
I literally have a plugin that gives that error. Its an anti ddos one. Ill disable it and see if it works. And my name isnt seth lol.
