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.
The "tarief" (price) filter on the site was incorrectly displaying filter options that no longer had relevant results. Even when no posts matched a certain price range, the filter option still appeared.
Solution:
The issue was caused by a mismatch between the field type and the filter type. The price range field was originally set as a radio button, but the filter was using checkboxes. Changing the field type to checkboxes resolved the issue, ensuring that only relevant options appear based on available posts.
