Symptoms
On servers running the Calendar and Contacts Server (CCS) plugin, users receive an internal server error when attempting to add a new calendar, and the following error may be found in the cPanel account's .php.error.log.
PHP Fatal error: Uncaught Sabre\HTTP\ClientException: <url>
malformed in /usr/local/cpanel/base/3rdparty/roundcube/vendor/sabre/http/lib/
Client.php:32
Description
When using Roundcube with the CCS plugin installed, the CalDAV plugin in Roundcube takes over the add calendar functionality. The CCS plugin only allows one calendar per user, but without CCS more calendars can be added in Roundcube. Trying to add a new calendar with CCS installed returns an error, as this functionality changes when installing CCS.
Workaround
Removing CCS allows the add calendar button to work successfully. However, without the CCS plugin installed, CalDAV functionality is also removed.
Upgrading cPanel to version 120 or above will fix this issue and retain the functionality once provided by the CCS plugin.
