When trying to add Translation the following fatal error occurs:

Fatal error: Uncaught Error: Call to a member function get_source_language_code() on bool

Solution:

- Backup the site completely to prevent any issues and for a reference point.

- Go to: WordPress Dashboard -> WPML -> Support page, Click on the "Troubleshooting" link there
