Civix rebuild required

[webmaster-cses-org-uk]

This extension is not compatible with CiviCRM 5.74+ (I think, upgraded from 5.72.1 to 5.78.3) due to Smarty changes.

Attempting to load CiviCRM with this extension active results in the following error:

Cannot access protected property Smarty\Smarty::$template_dir

This seems to be related to old code in the civix.php file, specifically in the _civix_civicrm_config() routine.

  if (is_array($template->template_dir)) {
    array_unshift($template->template_dir, $extDir);
  }
  else {
    $template->template_dir = [$extDir, $template->template_dir];
  }

Looks like a civix rebuild is required. This code does not feature in later versions.
