Plugin Dependency Check
The theme assumed WooCommerce and other WordPress plugins were active, causing PHP warnings when they weren’t. Logic was updated to safely verify plugin presence before executing related code and to ensure WordPress function calls in the dashboard don’t fail.
Shortcode Issue Resolved
A broken rendering pipeline prevented shortcodes like [member_logged_in_title] from appearing. Fixing upstream errors restored their functionality across template files and post or page content, making sure embeds and lazy loading images show properly.
Fixing the Meta Logic
The “Hide Featured Image” toggle wasn’t working as intended due to incorrect handling of serialized custom fields. The logic was updated to properly read and apply the toggle across all WordPress site posts, ensuring featured image 0 / 3-15 and thumbnail display correctly, regardless of file permissions or image size.
Removed Hardcoded Limits
The visibility rule was oddly restricted to post IDs over 29997. We eliminated this condition so the toggle now works for all posts, whether in media library, archive.php, or new post pages, and respects customizer settings, functions.php logic, and block editor previews.
Final Outcome
✅ PHP warnings eliminated
✅ Featured image toggle now works everywhere
✅ Shortcodes and embeds function normally
✅ Page editor UX simplified by aligning toggle behavior

Frequently Asked Questions (Solving Featured Image Display Bugs in Custom WordPress Themes)
Why is my WordPress featured image not showing properly?
Your WordPress featured image may not show properly due to theme limitations, incorrect image size, caching issues, or plugin conflicts. Check if the theme supports featured images, regenerate thumbnails, clear cache, and deactivate plugins one by one to identify conflicts. Correct settings usually fix it.
How to fix a broken WordPress theme?
To fix a broken WordPress theme, first switch to a default theme to isolate the issue. Check for plugin conflicts by deactivating all plugins, then reactivate one by one. Clear cache, update WordPress, theme, and plugins, and restore a backup if needed. Custom code may require debugging.
How to make a featured image responsive in WordPress?
To make a featured image responsive in WordPress, ensure your theme uses the_post_thumbnail() with proper CSS. Add img { max-width: 100%; height: auto; } in your stylesheet or use a responsive image plugin. WordPress’s built-in srcset usually handles different screen sizes automatically.
What is the best size for featured image?
The best featured image size for WordPress is typically 1200×628 pixels. This size works well for blog posts, social media sharing, and responsive themes. Use optimized, high-quality images with a consistent aspect ratio to ensure proper display across all devices.
