<b>Background of the issue: </b>
I am trying to add the Danish language to my site hidden link using WPML.
<b>Symptoms: </b>
I am trying to add the Danish language, but when I do this it keeps loading and I get a 503 error. So it is not possible to add this language (or any other language).
<b>Questions: </b>
How can I fix this error so I can add the language?
While one of my teammates takes care of your ticket, I will provide you with the first debugging steps.
Does the same issue occur if you temporarily deactivate all plugins except WPML? Is the problem only with Danish or does it happen with any language you try to add?
