The warning will read something like this:
PHP Warning: Attempt to read
property "post_type" on null in /wp-content/plugins/give/src/DonationForms/Actions/PrintFormMetaTags.php on line 18
To fix this temporarily, turn off DEBUG mode in the wp-config.php file. DEBUG mode is usually meant for development or staging sites, not live ones.
You can do this by accessing your wp-config.php file via SFTP or through your hosting provider’s file manager. Look for this line:
define('WP_DEBUG', true);
Then replace it with these lines:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors', 0);
Remember, this approach is for development environments, not live sites.
If you need help, your web host can assist you, and there’s official documentation available here: WP_DEBUG Documentation.
