Is there something that I can do about this or should I neglect it because it's coming from a search engine?

Thanks in advance.

Looks like you are running URL Master and Active Social Vanity URLs. You can ignore the error.

Ok, thanks. I'll look further into the not rewriting on the Active Social profile/group pages with the URL Master module.

I am not using Vanity URLs but I still get these errors. Should I ignore them too?

It is impossible to get this error without vanity urls installed. If you aren't using Active Social vanity urls then you should remove the entry from your web.config file.

Oh.

Ok now I am using vanity urls for groups but not for profiles. I havesetup URL Master to not rewrite urls for groups page. 

I am still getting this error. I am not using urlmaster on my website. I have uninstalled it. I am using vanity urls and they work. However, I keep getting this error in thousands.

I know you have asked me to ignore it, but I can't. This error is as annoying to me as this thread (update) is to you.

There has to be something wrong and how can I fix it?

Thanks for your patience.
