Hey all i was going through my error logs and noticed this:

[Sat Oct 24 12:57:05 2009] [error] [client IP Address] File does not exist: /var/www/vhosts/url/httpdocs/shop/includes/modules!-- end of the nav , referer: http://www.url.com

Is this someone trying to exploit zencart? theres also another similar url screw up again with a different 'non-url' and when i go to check using developers tools i can't see any reference to the place where the issue is, except a similar bit of code in the shop header, but its not exact.

any ideas?

Andy
