I can't get this running.
I have SS 3.1.4 and installed the latest userforms but it doesn't work.
Everytime I want to add UserForms page type it gives me an error in line 780 on SSViewer.php.
I've tried to install older version for SS 3.0, but it gives exactly the same results.
If someone knows how to help I would really appreciate that!
Of course I've done dev/build and flush=all in admin area - but still nothing.
