Thank you Gardner for your replay.
I use T3 framework version 2.4.5 in association with T3_bs3_blank version 2.1.8. The Joomla version is 3.4.0
Me too I've duplicate the issue on my local sites hosted by wamp server and the problem is still the same: all the megamenu configurations return to the default settings after saving any changes of the megamenu.
In the other words, it's impossible to work and save on the megamenu.
The only way to restore to my original configuration is importing the backup of the menu table in phpmyadmin.
The same issue occurs if you rollback with the JA Extension Manager to another previous version of T3 and T3_bs3_blank, so I think that there is a conflict between Joomla 3.4.0 and the T3 framework.
I have prepared for you an online simplified test version of my site (without images) with fresh installations of joomla 3.4 and T3 last version.
It is simplified but enough to give it a try.
Please give me your personal email address in order to provide to you the admin account or contact me at

But I think that this is a general problem made by anyone.
Try yourself:
1) first, in frontend, see the original megamenu structure made by me
2) after, in backend, simply click "save" in Administration>Template Manager
3) finally, in frontend, see again the megamenu structure.
You will realize that the megamenu is totally changed and the original structure made by me is lost.
