Background of the issue:
I am experiencing a fatal error on my site hidden link, which is related to the WPML Multilingual CMS plugin. I received an email from NameCheap indicating this issue. I found some information that suggests the error might be due to translation loading for the bridge domain being triggered too early. The error messages and debug info are provided in the report.
Symptoms:
Fatal error caused by the WPML Multilingual CMS plugin. Notice about function _load_textdomain_just_in_time being called incorrectly. Deprecated warnings about dynamic property creation in wpml_cms_nav_cache. Warnings about headers already sent.
Questions:
What is causing the fatal error related to WPML?
How can I resolve the issue with translation loading being triggered too early?
Only the main language (English) shows, all other languages and pages give error 500 and so on, see eventbooking.top and check the pages, you see.
