Problem: Update Failed: undefined

Solution: 1. Please take your full site backup.

2. Deactivate the existing WPML plugin.

3. Delete the plugin files – this does not delete your translations. You will simply delete the plugin files from your "wp-content/plugins" folder, NOT the database records.

4. Download the updated plugins from our servers (https://wpml.org/account/downloads/) and upload them to the plugin directory.

5. Activate the WPML plugin and add-ons.

I can not update the plugins, when I clicked update, it says "Update Failed: undefined". Other plugins don't have this issue. Could you please help?

Thanks
