PHP 8.1 Deprecation warning

It looks as though class elp_cls_dbquery is triggering the warning: “Optional parameter $limit declared before required parameter $emaillistgroup is implicitly treated as a required parameter”. I spotted it in one of our multisite sites that has a separate issue with w3-total-cache but thought I would raise it. It should be easily solved by making $emaillistgroup the first parameter for the relevant method(s). Hope that’s of use.
