There are some cases when at a certain moment something breaks on the WordPress site. One of the possible reasons is a conflict of installed plugins. If we cannot disable plugins in a productive environment, it will be convenient to use the plugin (yes, another one) Health Check & Troubleshooting. It is available at https://wordpress.org/plugins/health-check.
Install and activate it. After activation, in your WordPress dashboard, go to Tools – Site Health – Troubleshooting. Turn on this mode. All plugins will be disabled, but only for us. Other users won’t see this changes. It will also switch to the standard design theme.
Check if the error is gone. If the error persists, the problem is not with the plugins or the theme. If there is no error, then go to the Plugins menu and activate the plugins one after another. After each activation, check for an error:
- If all plugins are already enabled, and the error has not appeared, the problem is in the theme.
- If an error suddenly appeared after the activation of the any plugin – congratulations, we have found the culprit. Try to change the plugin settings, reinstall it or replace it with other.
At the end of this process, you need to turn off the troubleshooting mode. To do this, go to the WordPress Console – Dashboard – and click on the Disable Troubleshooting Mode button. It is located in the top of the screen.
