Submit error (500) with Storyboard
I am receiving the error message 'Submit error (500)' when trying to use a created Storyboard.
Attached are screenshots and log files where I replicated the error. I've tested all other parts of the instance and it is only affecting Storyboards as far as I can see.
I've also been through the cache options and logged in with multiple browsers in private/incognito modes that have been mentioned in other posts.
This is quite urgent with the client as their licence renewal is due and we are wanting to take up to at least 20 users. This issue is a showstopper to that.
