Only the upstream host may re-enable the feature; this requires root (system administrator) access that only the host would have.

When logged into cPanel (not webmail) it should display the version number in an area on the side (left or right usually) nearby other stats like disk usage and bandwidth usage; however, if it is not seen, I would try the following. After having logged into either cPanel or Webmail (and before loading Horde, Roundcube, or SquirrelMail), use the browser to view the HTML source of the page. At the very bottom of the page source there should be an HTML comment that includes the full cPanel version and build number.
Here is an example of the area in the page HTML source that includes the full version and build number; in this example I used "$version" to indicate where to locate the needed information:
Additionally, if your hosting service provider can provide you with a cPanel ticket number or other cPanel reference number (e.g., such as what may be provided via a ticket) then we can use this to follow-up internally and check on the status of the case.
