we have problems with cornerstone. First, it's a completly fresh installation of Wordpress, the only modification is setting the Memory Limit in wp-config.
On oure Staging site, we test the updates of the Theme and cornerstone, the last version thats worked on our main site is Theme Version 5.1.1 and cornerstone 2.1.3. The problem is when we try to edit, the editor loads endless and it stops loading at cornerstone-endpoint. We have talk to our host, and they say that the script set the database to sleep and does not response.
