I have a Joomla K2 site (all latest versions) and I have noticed that google is finding URLs like this one : http://mysite.com/tag/some-defined-tag.html

Problem is, that gives 404 error because Joomla doesn't know which component that URL belongs to.

Tags do work if they are appended to some page that has K2 component enabled like this: http://mysite.com/some-k2-category/tag/some-defined-tag.html.

Now, the main mistery is, how the hell does Google even find those links. I was looking all over the page and there was never such link that isn't connected to some category.

Is there some way I can fix this to actually lead to a proper page that displays all tagged content without 404 error?

[Edit] I have found out that my tag cloud is generating those non functional URLs but that wasn't the case before I have turned on SEF URLs. Any ideas on how to fix this?
