phpMyAdmin not working for user accounts only

Hello,
I cannot access the phpmyadmin from any of the user account while i can access the phpMyAdmin from the root account. When i try to open it from user account it says 500 internal server error.
I even tried to take a look at my error_log file but there is no information regarding that in the error log file.

Please tell me how this can be fixed.
Thanks
