Meet Gavern 1.2 and J! 3.1.5 - Layout manager wont save

Meet Gavern 1.2.3 and J! 3.1.5 - Layout manager wont save anything
When I try to make a layout change, for instance add a module position or row, I just get back to "Template manager: Styles". With no error. I can save everything else as it seems, configurations, json etc.

What to do?

Regards, Mats

Developers are aware of this bug and they are preparing a new release and currently it is in testing stage.

info regarding bug, although Joomla 3.1.5 update was supposed to be a security update but they have also changed certain styling which effects this template layout manager.

Please keep an eye on release updates.

See you around...

Ah that explains it. Thanx.
