I'm running a blog at mmogypsy.com and lately more and more commenters tell me that they cannot leave comments but instead are re-directed to 404 error. the issue here is that this only happens for 'some' people and not others(!) it doesn't happen to me on any computer - which also makes it tricky for me to see if I fixed the issue.
I've already looked this up plenty and can rule out permalink issues or browser-related issues. wp-comments...php files exist on the server and so does .htaccess. I can also rule out plugins as I haven't installed anything in a long time.
Is there a chance that this issue might be host-related (I am using namecheap) or else exist at the user's end? can anyone else think of a fix that might work? many thanks!
