FOUND A SOLUTION!!!!

hope this helps the others of you that ran into my same problem. I found the following suuport thread, and I’ve copied the specific bit which got my preview/customization back:

here’s what I changed:
Go to Settings -> General settings

Check WordPress Address (URL) and Site Address (URL)

The default should be https://yourdomainname.com

DO NOT add or change to something like https://www.yourdomainname.com

somehow the WOrdpress Address was set to the www variation. removing that fixed everything!

Agreed – I still search around and see many threads but no solutions. Is this really the only support path for WordPress?

I have no idea what to try to resolve this. The only thing I could think would be have my host delete the entire WordPress directory and re-install completely from scrtach.

If I need to do that, I’d love input on how to retain my posts, since I’m getting pretty up there and would hate to lose anything. ??

Currently have the following (I did disable them all and still had the blank page result though):
Akismet
All in one Favicon
Google XML Sitemaps
Insert Headers and Footers
Jetpack by WordPress.com
W3 Total Cache

Today I also installed Updraftplus – Backup/Restore just in case in playing around I accidentally did harm.

Everything previously worked fine with all these plug-ins installed.

Very recently though I had installed something like WPTouch, but have since removed it. I’m not sure if that installation/removal played in for the issue, as I am not certain when it specifically started.

i wanted to just play around at first to see what changes I could make, then I wanted to use the Live Preview to see how it would look on some of the other default themes.
so i guess I am not totally sure what I would like to change yet, but without the ability to see and/or customize anything I cannot figure it out either. ??
earlier i also tried uninstalling one of the other default themes and then re-installing (believe I used twenty twelve). still no luck.

apologies.
