Today I found that the Cornerstone page builder on my X-theme WP multisite will not display any content in the preview section on any page. More troubling however is the fact that if I make any changes to the properties sidebar, I am unable to save them. When I attempt to save, the green progress bar gets to about 99% on the top of the screen but then never get any further.
Everything was working fine yesterday, the only edit I made yesterday was upload a less than 2MB image to use as a background for one of my page sections.
I appreciate any help you could provide, my company needs to make a major business announcement in 2 weeks and we are unable to make changes. Please help!
