Error Cannot redeclare class modMaximenuckhikashop

I am trying to update a site but I receive an error when I try and open a Maximenu CKmodule to make some changes in the back-end admin.

Hi
Please check in the module folder if you have a file called "helper_hikashop.php", if yes, try to rename it to disable it and tell me

Hi CEd

Thanks for the quick response.
The file did exist and after renaming it I can access and edit the module.

PS : also check the options in the module to be sure that you have selected a category to load
