Strange thing is that- when I login as a registered member and post new thread; it works fine.
I tried to create new user and giving it administration power and then tried to post new thread but same errors appears. It is working with registered users but not with admin.

I have tried all means but failed. Errors seems to appear all of sudden, I haven't altered anything.

can someone help where to look.

MyBB does not use cgi-sys folder, nor does it have a file called amplugin and it does not use the shtml file extension.

This is an issue with your server/host or some other script you are running. It is NOT a MyBB issue
