Thank you for contacting WPML support!

Can you try the following?
- Deactivate and delete all the WPML plugins from your site (your content and translations will not be affected)
- download the latest versions from here and install them

According to provided debug information, your current versions are white updated (e.g. WPML is 4.0.8, etc).

Let me know if the issue is still there after you upload the latest versions.

Please make a full backup of your site before trying this or make these changes on a staging/development site!

You can use plugins such as UpdraftPlus WordPress Backup Plugin ( or ask your host to perform a site backup.
