EasySocial Kill 404s, Adopt Missing Pages

Hi StackIdeas,

First I would like to great you! Latest EasySocial seems to be very fast in combination with Joomla 3.3.0, especially during the time of traffic spikes and high number of simultaneous connections!

Again, I am hitting a very odd issue. It appear that EasySocial activity stream have completely replaced Joomla 404 pages. Every missing link and page seems to be redirected to Activity Stream. Here are some examples:

etc...

I've migated to Joomla 3.3.0 and there aren't any other problem excepts this one, which I think is pretty big issue.

Any idea why 404 pages are completely replaced by EasySocial stream?

I decided to uninstall everything and made clean install after that, but it didn't fix the problem.

Kind regards
Kal
