This warning is generated because the plugin is currently not programmed for explicit PHP 8 support. A direct response received from the plugin developers indicates that an update will be made “with a future iteration”, although no timescales can be given.
Hi Mark.
This is Nikola from the ManageWP support team. I can see that you reached out to us earlier via a support ticket, and that the team provided the necessary information. While the latest 4.9.14 version of the Worker plugin should be fully compatible with PHP versions 8.0 and above, there might still be some things that can cause issues. Our team is working on fixing this, and we hope that it will be fixed with the next version of our plugin.
Kind regards.
@nikolasavkovicmwp, same issue here, my server is running PHP 8.0.26.
