Problem: The client encountered a 'Critical error' on their website while a page was open in the browser. The error was related to the WPML plugin and was caused by a missing auto-increment on a primary key in one of the database tables. Solution: We recommend checking the ICL tables manually to ensure that they all have at least one primary key and that they are set to auto-increment. This also applies to the
wp_options
,
wp_post
, and
wp_postmeta
tables, which should all have a primary key with auto-increment. If you're experiencing this issue, please verify these database table configurations.
