On the main Community Answers page, the three buttons with the links:
/index.php?option=com_communityanswers&view=answers&task=resolved&Itemid=250
/index.php?option=com_communityanswers&view=answers&task=open&Itemid=250
/index.php?option=com_communityanswers&view=answers&task=popular&Itemid=250
/index.php?option=com_communityanswers&view=answers&task=mostansered&Itemid=250

Opens to the right pages.


However when I turn on Serch Engine Friendly URLS in Global config, when I access the buttions via the new URLs:
/ask-an-expert/answers/resolved
/ask-an-expert/answers/open
/ask-an-expert/answers/popular
/ask-an-expert/answers/mostansered

I get the following 500 error:

500 - Controller CommunityAnswersController not found!


SEF URLs works fine with all other components. I am using CA 1.6 that shows 1.5 in the backend. Joomla 1.5.18 PHP 5.2.6.

I can use the system without the SEF on for now, but I need to find out the root cause for production.
