FYI - I found & downloaded 5.3.6. I installed it. But I tried a different location as well on the server. It installed & worked just like the installation video.
The new location was in the subdomain's public_html folder. So perhaps that is causing apache & pulse to get long better, but not sure. As I had to change the subdomain's landing director in all instances.
I will see if I can upgrade to 5.3.8 a little later. But I wanted to let you know that bit of info.
Update:
I updated to 5.3.8 & same result. blank white page after install.php is kicked off. No admin console loads.
So I wiped the directory again. This time uploaded 5.3.7. I had thought the version history was inclusive of the latest. But realized after the fact the latest is top of dashboard & older is in the version history. I screen shot the health check after 5.3.7's install.php finished.
extracted the zip file, ran install.php, go the health check page. Admin console works just fine. So something is off with the 5.3.8 version. I am attaching PDF that shows the 5.3.6 to 5.3.8 upgrade process. I added the zip file, then got a listing of the file contents, and then update button.
