Extension cannot be installed on newer versions of CiviCRM 5.77.1 or newer due to Smarty4, Smarty5 incompatibility.

Unable to load template 'file:CRM/Cronplus/Admin/Page/Job.tpl' in 'file:CRM/common/CMSPrint.tpl'

By default, Smarty4, Smarty5 are enabled in civicrm.settings.php as shown below. These lines need to be commented for this extension to work.

/**
 * Specify a Smarty autoload file.
 *
 * Smarty5 is the version of Smarty we are in the process of adopting. To enable it
 * un-comment the line describing the path. Note that this will become always enabled in
 * the near future - this opt-in setting is transitional.
