What a pain but I was able to struggle through it.
I was on CentOS 5 running some ancient version of Media Wiki (1.11 something)
After a series of upgrades here and there, I was finally able to get it to a version that I believe will run on CentOS 7.
Spinning up a CentOS 7 instance now to test it out.
Another amazing thing I got done today was get a couple of more sensor at home up and running and added to my network.
