We have lately experienced that the Pro tab in backend CMS isn’t working. I can click edit with cornerstone from the all pages view but not the Pro tab on the specific page.
Seems to be following file that is reporting in the console:
/wp-content/themes/pro/cornerstone/assets/dist/js/admin/dashboard-post-editor.js?ver=1511007374

We also have issues loading page templates, I needed to save all new fresh templates.
