Tried them all. Fabrik and Joomla are the way to go, if you want to dive into Rapid Application Development.
This version corrects the Admin issue introduced by V4.4. V4.4.1 is available through the Joomla Updater or for download through your My Downloads area of our website.
Turns out a code change intended for our 5.0dev branch inadvertantly got pushed to the 4.x branch (by me, duh!). The javascript structure in 5.0 will change considerably and part of that change took effect with the inadvertant code change.
We have reverted the code change and released 4.4.1. V4.4 has been retracted.
Sorry for any inconvenience.
