Is the problem about permission? what must i do to solve this?
last before, i think the problem is because i install vqmod on my localhost and upload it to my server without re-install the vqmod.. right now i have delete vqmod folder and made my index.php and admin/index.php to original before, but still, the problem occurs.. im using shoopica template yet..

Please help !! I cant find the solution till now >.<

best regards,

robz

Problem solved : check the rekursif checkbox when change permission into 777 , i dont why i have to do that but it works well >.<

Thank you!
