Background of the issue:
I am trying to resolve a registration issue with WPML. The problem has occurred on other sites and was solved by cloning a new page, but that is not an option now. WPML registration is successful, but when I add add-ons like ACFML, the registration code changes to ******UvRp, and I can no longer install anything. ACFML also disappears from the list of add-ons that can be added. Deregistration does not work either, or if it does, this registration code is entered again and again (******UvRp). We do not use this code on any of our sites. Link to a page where the issue can be seen: link nascosto.
Symptoms:
ACFML cannot be installed, so I cannot translate custom fields. The registration code changes unexpectedly, and deregistration does not resolve the issue.
Questions:
Why does the registration code change when I add add-ons like ACFML?
Why does ACFML disappear from the list of add-ons that can be added?
How can I resolve the issue of the registration code being entered repeatedly?
