Hi,

 

Prestashop version is 1.6.0.14

I have to mention that I cleared out smarty cache.

I have a problem with module list in admin. When I click "read more" link below each and every modules, I receive this kind of errors when popup window appears:

Notice: Undefined property: stdClass::$price in /public_html/controllers/admin/AdminModulesController.php on line 1605
Warning: Cannot modify header information - headers already sent by (output started at /public_html/controllers/admin/AdminModulesController.php:1605) in /public_html/classes/controller/AdminController.php on line 1595

Another kind of error below:

Abandoned Cart Reminder Pro

Notice: Undefined index: id_currency in /public_html/cache/smarty/compile/c8/ca/da/c8cadaa68886a66f017b2de88540d1923b07e563.file.quickview.tpl.php on line 75

Notice: Trying to get property of non-object in /public_html/cache/smarty/compile/c8/ca/da/c8cadaa68886a66f017b2de88540d1923b07e563.file.quickview.tpl.php on line 75

Warning: Cannot modify header information - headers already sent by (output started at /public_html/classes/controller/Controller.php:468) in /public_html/classes/controller/AdminController.php on line 1595

Please help me!
