Hi,
When I’m trying change something in product, after submit script returns error like below:
Notice: Undefined index: customer_group_id in D:\xampp\htdocs\controlsystems\system\storage\modification\admin\model\catalog\product.php on line 208Warning: Cannot modify header information – headers already sent by (output started at D:\xampp\htdocs\controlsystems\admin\controller\startup\error.php:34) in D:\xampp\htdocs\controlsystems\system\storage\modification\system\library\response.php on line 17
Could you please advice? Opencart Version 2.2.0.0

Hi,
This error doesn’t look to be theme related. Can you try to enable the default theme to check whether it will appear again? You can also try to disable all modifications in Admin > Extensions and clear cache.

You should be able to identify which one is the trouble maker.
