Why is "WordPress" disabled when creating a new host?
If you create a new host and the host type "WordPress" is disabled, then this can have several reasons. But often it is the case that you have selected a too old PHP version as default version. So just select a newer PHP version (see Languages > PHP) and then try again.
To find out the exact reason why the host type "WordPress" is disabled move the mouse cursor over the WordPress icon and wait a short moment. You will then see a tooltip informing you about the reason for the deactivation.
