Thank you for contacting the support forum.
Before your ticket is assigned to one of my colleagues, please allow me to walk you through some initial debugging steps. This will help speed up the support process.
The cause of the issue is mixed database table collations. You can reach out to your host/developer to follow these steps:-
- Make sure you have a complete database backup
- Go to the database and check columns of wp_icl_strings table.
- All columns should have the same collation and recommended is utf8mb4
Thanks
