After the elevate process from CentOS 7 to AlmaLinux 8 the WP-Toolkit may be missing (if this is the case you will get a 404 error when clicking on the WP-Toolkit link in cPanel). To fix this login to WHM and go to 'Terminal'.

Then type: 

sh <(curl https://wp-toolkit.plesk.com/cPanel/installer.sh || wget -O - https://wp-toolkit.plesk.com/cPanel/installer.sh)

This will reinstall the latest WP-Toolkit version, and immediately make it available through cPanel.
