[SOLVED] Plexmediaserver Issue

Hi. I'm constantly learning (from my mistakes) with Slackware 15.0 and love the way that the user can store .tgz and .txz package files once compiled and install them on a fresh Slackware installation. I've recently done this with plexmediaserver which I cannot get to run. I have followed the instructions and created the necessary group and user as per the slackbuild readme, I have also chmod 755 the rc.d plexmediaserver again as per the instructions. The localhost refuses to connect even after a reboot. Therefore the only conclusion I can draw is that "something" is missing. I installed Avahi and enabled it, thinking it might be that. No success. The only other thought I had is - does localhost require something which I do not have to make it work. Research suggests Apache server, perhaps? I would appreciate any thoughts on my dilemma, please. BTW I would not have a clue on how to install Apache server if that is the missing component. Thanks for reading this and any advice.
