Why did OpenCart 3 stop opening the product card page?

Question

opencart

Hello. There is a site on OpenCart 3.0.2.0. It does not open product cards. At first it just gave an Eroor 500 error, then I turned on the display of errors in the admin panel and this appeared on the product card page:

Notice: Undefined index: show_product_attr_group in /home/c/cu16226/opencart_1/storage/modification/catalog/controller/product/product.php on line 434
Notice: Undefined index: show_product_attr_item in /home/c/cu16226/opencart_1/storage/modification/catalog/controller/product/product.php on line 435

Notice: Undefined index: product_banner_position in /home/c/cu16226/opencart_1/public_html/catalog/controller/extension/module/uni_product_banner.php on line 7

But the most interesting thing is that there are similar errors on the main page, but it works:

Notice: Undefined index: sticker_new_date in /home/c/cu16226/opencart_1/public_html/catalog/controller/extension/module/uni_stickers.php on line 48

What could be the matter and how to solve the problem?

This is not an error, but just warnings, I have seen this on many sites, your problem is somewhere else. Try to regenerate modules.
