mikew, Php 7.4 produced the following error message, “This version has reached EOL. [Learn More](https://php.net/eol.php). We strongly recommend that you use a version that is still supported upstream. If you do continue to use it, you will be susceptible to any remaining bugs or security issues.” See the screenshot error message: ![2023-07-17 04.54.54 whm.devced.com 8c826f71208d](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/a/a58c22727fc6ef44d5d2cb7c4e3dc69c0c49da6c.png) Do you have any further suggestions?

To use Mautic, you will need to downgrade to an earlier version,” [https://mautic.devced.com](https://mautic.devced.com) I downgraded the php version to php 80. Read the following error message," We have detected some minor things that we recommend changing in order to have a better Mautic experience: It is recommended to secure your installation with an SSL certificate (https).
