I can't work on the site at all until I get this resolved.
I installed MaxCDN in connection with the W3 Total Cache plugin. Now Cornerstone isn't showing up at all as an option when I go to create a new post. The Cornerstone icon shows up when I click on the link under X at the top of my Dashboard, but it doesn't load. Any suggestions? I cleared the cache for W3 Total Cache and I purged the cache on the CDN section of W3.
UPDATE: I just went through the latest updates step by step on my other website that uses X + Cornerstone + W3Total Cache + MaxCDN. Cornerstone is still working great after all the updates -- except the one update I didn't make was updating Cornerstone itself. So it's working as version 3.0.4 but not as version 3.1.2 (which is on my other site now).
Can I reinstall version 3.0.4 on the site that isn't working? And if so, how do I do that?
