This will recreate the missing image sizes for all media files and repopulate the necessary metadata (`width`, `height`, etc.). 2. **Check Attachment Metadata in the Database** Sometimes the image metadata stored in the database (`_wp_attachment_metadata` post meta) might be missing keys. You can inspect this via a database tool like phpMyAdmin or using code via ` get_post_meta( $attachment_id, '_wp_attachment_metadata', true )` to verify. 3. **Ensure All Required Image Sizes Exist** If you’ve recently switched themes or added custom image sizes, make sure all expected image sizes are correctly registered using `add_image_size()` in your theme’s `functions.php`. 4. **PHP Version Compatibility** If you’re running on PHP 8+, these warnings will appear more often than before due to stricter error reporting. You can suppress these warnings in development by setting `WP_DEBUG_DISPLAY` to false in your` wp-config.php`, but **do not ignore the underlying data issues in production**.` define('WP_DEBUG', true); define('WP_DEBUG_DISPLAY', false);` Viewing 1 replies (of 1 total) The topic ‘php error’ is closed to new replies. * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 2 replies * 2 participants * Last reply from: [Aditya Singh](https://wordpress.org/support/users/iamadisingh/) * Last activity: [1 year, 2 months ago](https://wordpress.org/support/topic/php-error-690/#post-18458285) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
