Cornerstone will not load or work. I am running them v7.1.2, the latest according to APEX, in child-theme. When I click on customize I simple get a spinning icon and nothing loads. When attempting to open the customizer all I get in the URL bar is https://MYDOMAIN.de/#/options. The URL to my site itself is https://patrickcomtoisphotography.com/blog. I have looked at other solutions in the forums and have tried troubleshooting myself by doing previous suggestions like disabling all the plug-ins, switching to the main version and I still get the spinning icon. I get the same result irregardless of the browser I use. It happens with Chrome, MS Edge, Firefox and Opera. Not sure where to start and if I cannot customize my theme, this becomes a major issue is continuing with the X theme itself. Any assistance you can provide would be appreciated.
