I have been creating custom languages with no problem at all. I am now trying to create a 'en-BE' custom language and suddenly the languages will not create, and I am left with the following error: 'Please, enter required data.' Even though I am filling in all the fields. Could you help please
I just checked your site. Regarding adding a new language, I cannot see the problem. I went to WPML -> Languages -> Site Languages, and added Irish as a new language that was not in the list of languages on your site. The process completed successfully, and Irish has been added. Please see the attached screenshot, irish-added.jpg.
Nevertheless, I can see the problem of not being able to change an 'hreflang' field. went to WPML -> Languages -> Site Languages -> Edit Languages, and changed the 'hreflang' field of the newly added Irish language from 'ga' to 'ga_IR'. But it failed with a warning.
