Hi,
That indicates that an invalid URL has been requested by someone on your website.
The big question here is why someone called that URL.
Because to call it, it must first know about it from somewhere else. And HikaShop doesn't generate that URL normally.
Looking at the HTTP_USER_AGENT parameter in the report, you can see that it's actually a crawler from bing, the search engine who is trying to request that page.
Check several reports and see if it's always bing. In that case, you want to go to
www.bing.com/toolbox/webmaster/
and check there what can be done to avoid crawling these URLs.
If it's also other crawlers, or even normal users with browsers, then there is still something on your website telling them these invalid URLs. The problem is I don't know where. One thing you could do is use the "redirection" component of your Joomla to direct the users and crawlers to another page of your website when they access these invalid URLs.
