I am using Magento 2.2.7 Can't visit product details pages or edit them if any image was added to product.
Also when I am login into admin part and go into Content - Configuration - Edit theme. Page loading infinitely. I have tried all browsers and have also tried to change theme in database.
I think that this could be related to Magento update or ssl certificate installation.
I wasn't able to find any helpful information in logs. Have tried to remove extensions. Have tried to flush cache. Have tried even to restore website from backup.
