If we have trouble, get notice after update whmcs to 6.0
Notice: Undefined property: Smarty::$_tpl_vars in /home/—/public_html/client/vendor/smarty/smarty/libs/Smarty.class.php on line 738
it’s simple to solve problem just disable notice from script Smarty.class.php on line 738
trigger_error(‘Undefined property: ‘ . get_class($this) . ‘::$’ . $name, E_USER_NOTICE);
give @ to disable notice
@trigger_error(‘Undefined property: ‘ . get_class($this) . ‘::$’ . $name, E_USER_NOTICE);
i hope this help 🙂
