Hello,
I am running X 6.3.8 and Cornerstone 3.3.8. I just updated to WP 5.0 and now the 'Update" button and all other edit options are missing. This is only for pages and post built in cornerstone.
I use W3TC and have purged all cache.
Here is image of edit screen for a page not built with cornerstone:

Please advise how to get the edit functions to return.
Thank you
