I am trying to update the plugins WPML Multilingual CMS, WPML String Translation and WPML Translation Management but i'm allways getting the error "Update failed: undefined". I have an official subscription and it worked everything so far. Why can't i update those anymore?

Thank you for contacting WPML Support.

Please try these steps:

- Go to Dashboard -> Updates
- Press the "Check Again" button
- Press the "Update" button at the bottom of the page

- Go to Plugins -> Add New -> Commercial
- Press the "Check for updates" button

- Go to look for your current key and erase it.
- Create a new one for your site.
- Go to Plugins -> Add New -> Commercial
- Click on the "Unregister WPML from this site" button
- Register WPML adding your new key.
- Try also disabling the "Keep up-to-date about which theme and plugins I use" option

If that does not fix the issue you can manually update the plugins.
❌ Before proceeding please make a full website backup! ❌
- Download the latest version of WPML from
- Disable WPML Multilingual CMS
- Delete WPML Multilingual CMS (the settings and the translations are saved in the database so they will not be deleted)
- Upload the freshly downloaded WPML plugin from Plugins -> Add New -> Upload Plugin
- Activate WPML

Please let me know if this solves the issue or if you need further help.
