gacott Oh thanks I really did not checked on the tittle dumb me. Anyways the requirements of Mautic may conflict with some versions of PHP, I mean, if people are running versions 7.0 for example, Mautic does not work on such, only 7.2.21 and up and PHP 7.4x is not supported at the moment and as you might know aaPanel has 7.4x version available so the implementation might not be so useful to many users, my advice is for you to create a third party deployment of that plugin yourself, you can check the how to in this link, I hope that helps you out.
