Plugin Conflict in Yoast SEO 19.7 Causes Fatal Errors and Site Crashes

November 11, 2022 | | Updated: March 24, 2023

Yoast SEO WordPress plugin version 19.7 conflicts with other plugins, causing fatal website errors. This is the third time a Yoast update has caused severe plugin conflict this year. The error was caused when the update’s coding conflicted with another plugin. Yoast 19.7 counteracted with other plugins that change the admin login URL. It is a security measure designed to prevent hackers or hacking software from attempting to guess user login password credentials. On identifying the problem, Yoast was prompt to tweet that the update, when used in combination with plugins or code that alters the default WordPress login URL, creates a fatal error. They also released a new update, Yoast SEO 19.7.1, with bug fixes within two hours of identifying the problem. Yoast advises users to update to this latest version to prevent crashes.
