I am testing out a Fedora28 platform for a possible replacement for my webtrees server. I have Fedora28 installed in a VirtualBox VM and have a working LAMP configuration. When I open the webtrees URL to do the install, I am getting the message that several needed modules are disabled (pdo, pdo_mysql and gd). I installed those modules and have confirmed that they are located in the same directory as the other modules ( usr/lib64/php/modules). I checked their respective .ini files in the php.d directory and updated each with the statement extension=modulename (i.e. extension=gd). After both restarting Apache and rebooting the VM I am still getting the same error messages from webtrees. Not sure what else to check.
Configuration: OS=Fedora28, Apache=2.4, PHP=7.2.9
P.S. All installs done with the default repositories.
