Background of the issue:
I am trying to translate my home page using WPML. The issue can be seen at the following link: hidden link
Symptoms:
I receive a critical error when I try to translate my home page via the translation editor. The translation of the page worked before but has now stopped working. I already removed the English version entirely to see if that fixed the issue, but with no result. When I click the plus sign to translate, the update icon keeps spinning.
Questions:
Why am I encountering a critical error when translating my home page?
What steps can I take to resolve the spinning update icon issue?
