This Webby guide explains how to complete the task described in How to fix a "There has been a critical error on this website." error.
A critical error in WordPress is commonly caused by a faulty plugin, theme, PHP version mismatch, or custom code issue.
Enable debugging, review the error details, disable the recently changed plugin or theme if needed, and test the site again step by step until the faulty component is identified.
If you are unsure which settings apply to your Webby hosting service, confirm the correct hosting, SSL, DNS, or WordPress details before making further changes.
