You can try making the query in comshow.php this
Code:
Content visible to verified customers only.
Personally I would simply add something like this to the robots.txt
Code:
Content visible to verified customers only.
Really the only way to get this issue since we do not present a link in the program for it is you have to have 0 comments and have a bot just playing with urls and filenames. Your seeing an error you never would see in the program because we do not give you a link with no comments.
