Yes, I'll fix the tour bug! One thing at a time
About the second screenshot. Just go to your configuration in the backend. Hotspots -> dashboard -> options. Save it again. After that the sql error shouldn't happen.
I had to change name to title (required for some joomla APIs), and we now also have an alias field (that's not used for the url right now, but we will move to it).
So your cancel button is doing what exactly? Just going back? It's not that simple. If the user has clicked once on save and they got an error, then some of the information they entered is saved in the session. Going back won't delete that information and if they try to fill in the same session, then the old information would be still there.
