I set up a wordpress site 4 years ago. Owing to server limitations, I was unable to update the site for many years, but have now been able to update to the newest versions of wordpress, the x-theme and cornerstone. However, I now find myself unable to edit posts in cornerstone, and when I go to the x-theme settings to try to edit the permissions and save them, I receive a message stating “Sorry! Unable to save”.
Might someone be able to give me a hint / indication of what I am doing wrong, and how I can re-enable editing of posts with cornerstone?
