please try to set _PS_MODE_DEV_ to true in file /config/defines.inc.php and try again to see what is the detailed error message.

The error seems from prestashop core files, have you made any custom changes?

What is the version of your Prestashop?

[benjaminlh]

the version is 1.6.1.1

I think we might have done something at some point, don't really remember actually.. 

 

What should I do if we have?

[shokinro]

You may try to roll back the changes by getting original version of the same file in same version of prestashop original package to replace it.

 

By the way, the best way is to create a override class and make changes to the override class instead of prestashop core file directly.
