WordPress Critical Error

If you get a WordPress “There has been a critical error on your website” error, you probably have an issue with a theme or plugin. The quickest way to troubleshoot is to rename the plugins directory since there’s no way to login. This technically disables all plugins. Rename it back to plugins and enable each plugin one by one.

Disable all plugins.

mv plugins plugins-backup

Login and restore the plugins directory.

mv plugins-backup plugins

Enable each plugin one by one and check if the site is broken.

Yum Repo Plugins

Here’s how to disable plugin in Yum repos.

# check which plugins are enabled
yum repolist
# disable plugins
yum update --disableplugin=product-id,subscription-manager
# check agin
yum repolist

If that doesn’t work, check the individual config files of each plugin.

cd /etc/yum/pluginconf.d/
vim product-id.conf
vim subscription-manager.conf

Disable it.

[main]
enable=0

WordPress Custom CSS Stylesheet

I’m releasing a new WordPress plugin called Custom Stylesheet. This plugin creates a safe haven for some custom CSS styles that you want preserved, even if you switch from one theme to another. In addition, this plugin also prevent theme updates from overwriting your custom styles. Lastly, this plugin also serves as a quick test environment for applying your custom CSS styles.

Install and Configure

  1. Upload the “stylesheet” folder to the WordPress plugins folder.
  2. Activate the “Custom Stylesheet” plugin from the “Plugins > Installed Plugins.”
  3. Custom Stylesheet is available from “Appearance > Stylesheet.”
  4. Add your custom CSS styles.
  5. Click “Save Custom Stylesheet” to save.
