How to check for the rewrite rules file? Where may I find it? And what can I do to resolve the conflicting issues. I use parallels plesk panel, though you ought to know, just in case.

check for web.config file at the main site folder & MyBB folder

I am not sure about conflicting security rules in web.config but you can also check whether MyBB system
is able to access showthread.php file by running file verification tool available at tools & maintenance
section of forum Admin Panel

Okay, so I couldn't find web.config file in both the main site or mybb directories but I ran the file verification tool as you said and it shows about a 100 files as missing, showthread.php among them. How do I upload these specific files? Or will uploading only showthread will make the website work?

No, I figured it out. It was showing almost all the files from the install directory which we are supposed to remove anyways. So I uploaded the showthread file and now it's working perfectly, thanks lot.
