Bigul Supporter Languages: English (English ) Timezone: Europe/Vienna (GMT+02:00)	Hello, Welcome to the WPML support forum. I will do my best to help you resolve the issue. I have reopened this ticket for easy follow-up, and it will help us to avoid discussing multiple things in a single ticket. We had a detailed test on our local copy. This fatal error is not trigging after the following steps. So please try it after a full site backup {mandatory} and make sure the bug exists or not. 1) Upgrade to the latest version of WPML (4.7.2) 2) Upgrade to the latest version of plugins like Disable Gutenberg & Gravity Forms 3) Go to WPML>>Support page, click on the Troubleshooting link (blue link in the middle of the page) 4) On the Troubleshooting page, please click on the following options of the Clean up section. Wait for confirmation of processing after each one. - Clear the cache in WPML - Remove ghost entries from the translation tables - Fix element_type collation - Set language information - Fix WPML tables collation - Assign translation status to duplicated content - Fix terms count - Fix post type assignment - Cleanup and optimize string tables 5) Clear all types of caches -- Thanks!
