Hello,
1) I suppose that your issue with the fatal error was caused by your changes in wp-config file, for example we checked it and found the following https://prnt.sc/qetklj – some “to” word and incorrect quotes. If you make any changes be careful and make a double check because it could cause errors.
2) I don’t see any notice for the product that has Auto https://gyazo.com/497aef50d99b6111f9d8ba685d8bba9b So, could you provide us with link to product where you have that notice and broken layout.
Regards
