[bonline]

Hi i am getting forwarded to the home page and seeing this error when i am browsing through some categories in the VM store. I am using joomla 2.5.24 :

Error loading component: , 1

Like is said this only happens when clicking into some categories.

Please help.

Sounds like a broken installation. But check first if you get the problem also without SEF.
