Hi:
I seem to be having a conflict with the new version of cornerstone and W3 Total Cache. Last summer I excluded the following three files from mimifying and everything worked fine
wp-content/plugins/cornerstone/assets/dist-app/js/cs-vendor.js
wp-content/plugins/cornerstone/assets/dist-app/js/cs.js
wp-content/plugins/cornerstone/assets/dist/js/admin/huebert.js
But the conflict has come back. cornerstone never displays the page content unless I disable W3 Total Cache and autooptimize.
Emptying the cache3 does not fix!
