When installing WPML (sitepress-multilingual-cms) on my website, it has been broken:
hidden link
I have received an email to the administrator which I sent to you and capture of the computer screen where an error message is displayed which I also sent to you.
This error usually happens because of corrupt entries or misconfiguration in the Database. Please try the following steps after creating a full database and website backup:
If you can still access your Dashboard:
1. Go to WPML > Support.
2. Click on the Troubleshooting link.
3. Click on the "Fix post type assignment for translations" button.
4. Click on the "Remove ghost entries from the translation tables" button.
If you can’t access or it does not help:
1. Open your database using phpMyAdmin(or another database manager)
2. Go to the wp_icl_translations table
3. Find the entry with element_id: 53
4. Delete that row
