steamon 2019-12-25 12:40 reporter ~0035890	I like to add that if I want to use page speed on Plesk I have to disable SELinux currently. This disables a part of the security of the OS. Can we get an ETA when this can be fixed? I know page speed is technically a feature and not needed to run Plesk or a Web server. Lately, Google search console is measuring page load speed and its feature is slowly becoming more important in the website's world. Has anyone tested CentOS 8 with this?

TrevorH 2019-12-26 12:17 manager ~0035896	We don't support systems with Plesk installed at all. However, perhaps you can fix it by reading the following links Useful resources for SELinux: http://wiki.centos.org/HowTos/SELinux \| http://wiki.centos.org/TipsAndTricks/SelinuxBooleans \| http://docs.fedoraproject.org/en-US/Fedora/13/html/Security-Enhanced_Linux/ \| http://www.youtube.com/watch?v=bQqX3RWn0Yw \| http://opensource.com/business/13/11/selinux-policy-guide \| http://freecomputerbooks.com/The-SELinux-Notebook-The-Foundations.html
