Hi Jairo.

To be honest those warnings does't refers to JomSocial but to Joomla, anyway it seems that, you've some kind of a redirection set on /administrator page, could you provide us with some valid url?

Hi

This is happening in the jomsocial component. When I uninstall jomsocial joomla works perfect with no errors.

Seems that one newsfeed tab in the admin (jomsocial backend) has a broken link. When joomla try to reach the news in this broken link the error appears, also making the system ultra slow.

I modified the code so the news tabs are not shown
