Hi!
I think I've found a bug that was introduced revently and isn't due to my coding :-)
I have an editable reporting using templates and when I have a field type="textarea" it fails when saving info (eg. using OK button or autosave on exit). This failure shows up in two ways:
1) When admin (or authenticated?) it jumps back to the dashboard
2) When unauthenticated it shows a login screen
Changing it from "textarea" to "autosize" solves the problem (after 4-5 hours of trying many other things!
