Blank page after update to 6.12.65-27

I just updated to 6.12.65-27 from 6.12.65-15. I progressed through each, like I was supposed to.
I have read other posts in reference to this issue, however they were for way older versions, so I thought I would post here, in case there is some known issue with the later releases.

I checked my httpd log and it was clear.

Any assistance would be appreciated.
