I was unable to add or edit content in WYSIWYG fields, as both the Visual and Text editors were not loading. The browser console showed a JavaScript error related to a missing file at /wp-content/plugins/types/public/js/compatibility/themes/modern/theme.js.
Solution:
The issue was caused by the official Font Awesome plugin. Disabling this plugin resolved the problem, allowing the WYSIWYG editor to function correctly. If similar issues arise, testing in a minimal installation by disabling conflicting plugins can help diagnose the root cause.
