The following error appears when I try to open a site in Parallels Web Presence Builder:
Error: For editing sites with Presence Builder, the hosting account must support PHP version 5.0 or later.
PHP is disabled in the domain where to the site is published.
Enable PHP for the domain. For Parallels Plesk Panel:
Home > Subscriptions > %domain.tld% > Websites & Domains > Hosting Settings
Enable option "PHP support".
