Hello,

I use prestashop version "1.0.0.8" and I move my website to new hosting company and hosting control panel and path different (Plesk to Directadmin) so I changed setting on setting.inc.php and frontpage run fine. but I can't login to admin panel only blank page show with no line error. I try to remove file from "compile" dir but it's not fix the problem.

My server info is

MySQL 5.0.77

Please suggest me how to fix this problem.

Thank you
