    Hello Everyone!

    cPanel & WHM version 76 is published to the STABLE release tier. This thread will serve as an overview of reported issues specific to cPanel & WHM version 76.

    Fixed in Version 76.0.7
    Case Number: CPANEL-23840
    Status: Fixed in version 76.0.7.
    Description: Using "whm.domain.tld" as the server's hostname results in the system using the SSL certificate associated with "domain.tld" when it's setup as an individual account.
    Workaround: Rename the hostname to something other than "whm.domain.tld". Note that service subdomains are not recommended for use as the hostname per the guidelines at:

    Change Hostname - Version 76 Documentation - cPanel Documentation

    Forums Thread: Pending Publication - [CPANEL-23840] hostname uses wrong SSL certificate

    Fixed in Version 76.0.5
    Case Number: CPANEL-23314
    Status: Fixed in version 76.0.5.
    Description: Accessing phpMyAdmin as a cPanel user in cPanel & WHM version 76 leads to the creation of pma_template_compiles_$user files in the system's /tmp directory instead of in the /home/$user/tmp/ directory (as with Roundcube and Horde).
    Workaround: See instructions in thread below.
    Forums Thread: [CPANEL-23314] CSF Suspicious File Alerts (/tmp/pma_template_compiles) after V76 Update

    Case Number: CPANEL-23793
    Status: Fixed by reinstalling the Let's Encrypt plugin.
    Description: cPanel updates fail with the following error message when outdated iterations of the cpanel-letsencrypt RPM are installed:

    ***** FATAL: Test install failed: error: Failed dependencies:
    cpanel-perl(CryptX) >= 5.22.1 is needed by (installed) cpanel-letsencrypt-2.16-6.1.noarch
    Workaround: Manually reinstall the Let's Encrypt plugin using the following commands:

    Then, proceed with the cPanel update:

    Forums Thread: [CPANEL-23793] Update to version 76 failed due to cpanel-perl(CryptX) >= 5.22.1 dependency
    Case Number: N/A
    Description: In cPanel & WHM version 76, we upgraded the PHP version used for cPanel & WHM (cpsrvd) from PHP 5.6 to PHP 7.2:

    Implemented case CPANEL-22332: Update cPanel internal PHP to upstream version 7.2.7

    As part of this change, a different ionCube Loader version is utilized. This change requires plugin developers to publish updates to their plugins that include files re-encoded with the newer ionCube version. Otherwise, the plugin will fail to load and generate error messages like this in /usr/local/cpanel/logs/error_log upon the upgrade to cPanel & WHM version 76:

    PHP Fatal error:  The file /usr/local/cpanel/whostmgr/docroot/cgi/plugin-name/index.php was encoded by the ionCube Encoder for PHP 5.6 and cannot run under PHP 7.1 or later.
    Workaround: See In Progress - Plugins stop working after upgrade to cPanel & WHM version 76
    Case Number: N/A
    Description: SpamAssassin may fail to start in version 76 if a custom or OS SpamAssassin version was manually installed on the system in the past. Attempts to restart SpamAssassin via "/scripts/restartsrv_spamd" will result in an error message like this in the output:

    info [restartsrv_spamd] The service 'spamd' failed to restart. Trying '/usr/local/cpanel/3rdparty/perl/526/bin/spamd'.
    …warn [restartsrv_spamd] The system encountered an error while starting the “spamd” service with the command “/usr/local/cpanel/3rdparty/perl/526/bin/spamd --daemonize --max-spare=1 --max-children=3 --allowed-ips=,::1 --pidfile=/var/run/”: The subprocess reported error number 255 when it ended.
    An error is also seen when running the /usr/local/cpanel/3rdparty/bin/sa-update command:

    # /usr/local/cpanel/3rdparty/bin/sa-update
    config: failed to parse line, skipping, in "/etc/mail/spamassassin/v310.pre"
    Workaround: Run the following commands via SSH as root to ensure the cPanel-provided SpamAssassin is utilized:
    1. /usr/local/bin/perl /scripts/perlmods -u Mail::SpamAssassin
    Or, if your system perl is in /usr/bin, use this command instead:
    /usr/bin/perl /scripts/perlmods -u Mail::SpamAssassin
    2. mv /etc/mail/spamassassin /etc/mail/spamassassin-backup
    3. /scripts/check_cpanel_rpms --fix
    4. /scripts/upcp --force
    Case Number: N/A - The plugin is not updated to work with the latest SpamAssassin version.
    Description: Incoming email will stop working on systems using Anti-spam DNSBL plugin by BOates upon upgrading to cPanel & WHM version 76. Here's an example of the error message visible in /var/log/exim_mainlog on affected systems:
    Workaround: Remove the plugin using the plugin developer's uninstall instructions:
