I have installed X into a subdomain on my site and all seemed to be going well as per previous use on the main site. After creating a new home page editing and so forth it all seemed fine. When I attempted to go back to the page and edit it started producing the 'A conflict on your front end of your site has prevented.." error.
I had only a couple of addons installed so deactived them - did not help.
I deleted the page, started again and again it worked fine over a period of time, Then next day, same issue.
I tried increasing the response time
Tried uninstalling Cornerstone and reinstalling.
Tried pretty much everything on support forums, check formatting, removing images etc.. but with no luck.
The strangest thing is that I can create and edit other pages, just not the home page. I have set different pages to the home page and they seems to be fine and can be edited - just not the actual 'home' page.
