Error 503 with sites on different servers

This is gonna be a long one, so get ready.

First of all, here is my setup (URL followed by theme and WP version):

thezeninvestor.com
Elegant Themes PureType 4.6 on WP 3.4.2

zenrent2own.com
zenlocationachat.com
homebridger2o.com
enfincheztoit.com
Elegant Themes Elegant Estates 3.9 on WP 3.4.2

cullinancondos.com
Elegant Themes Nova 2.2 on WP 3.4.2

phase2.lincolnheightscondos.com
Elegant Themes My Product 3.0 on WP 3.4.2

All of these Elegant Themes sites have had edits made to their stylesheets and headers, etc.

I also have a few other sites that do NOT have Elegant Themes running, namely:

https://www.lincolnheightscondos.com
applynow.homebridgeR2O.com
appliquez.enfincheztoit.com
enfincheztoit.com
wwww.woodhollowpark.com

Now … I have the first site, thezeninvestor.com on Cloud Flare. The rest are on GoDaddy under a single hosting plan.

Because it would take me forever to go through each site to check and see what’s wrong, I used thezeninvestor.com on Cloud Flare as my test.

I deactivated all the plugins for this site, and I also deactivated the PureType theme and activated the standard Twenty Eleven theme instead.

I’m STILL getting the 503 error.

I had thought perhaps it was a problem with the Elegant Themes theme, since I haven’t updated it in quite some time due to the edits (don’t want to lose them), but wouldn’t deactivating the theme and reactivating Twenty Eleven basically void that possibility out?

Any help you can offer is greatly appreciated. As of this moment, ALL of my sites are down … with the exception of one, https://www.royalparkway.com, which is actually a Blogger site … ??
