Hi John,
Sorry you’re having this much trouble, but this is really not an X Theme or Cornerstone issue. I did investigate the issue and found out that your site owns resources is blocking it.
Notice that screenshot, your site address is http://www.samiotes.com.php7-35.lan3-1.websitetestlink.com
But your resources is coming from www.samiotes.com
(which is a different site, right?), so your resources (JS & CSS) would be either Blocked or Not Found, so this issue is on how your staging site is setup, with that said please contact your hosting support on how you can get around with this.
It would be better if you can use your actual URL on developing the site and not the temporary URL. Or have a staging domain where you develop your projects.
I deactivate this plugins on your site (Autoptimize, Cache Enabler, WP Asset CleanUp) because there is no point on activating this plugins in development stage. You can also deactivate those other optimizer plugin if you’re not using them. You mentioned above that you have not added any plugins in this new site, then who installed this plugins?
Did our Guys on pinnacle@theme.co has get back on you? If not, then more likely they are working on a bigger project right now and have their hands full. If this is the case you can find freelancers X and Pro developer here (but keep in mind that those Guys are freelancers there is no way that they are connected to us, If you saw someone selling our theme or any theme there, then that is a rip off. )
Let us know how it goes,
Cheers!
