Community Q&A

Why does WooCommerce trigger a fatal error on activation?

Fatal errors during activation are often caused by conflicts with other plugins, theme incompatibilities, or syntax errors in custom functions.

How do I fix a fatal error after a WordPress update?

Check your error logs to identify the culprit, disable recently updated plugins, or roll back to a previous version of WordPress using a backup.

Can custom code in functions.php cause fatal errors?

Yes, moving custom code into a standalone plugin or modifying functions.php incorrectly can lead to site-wide crashes if the code is not properly tested.
