Hello.

It's Alpha version and it's not recomended to install such versions on Live sites if you aren't ready to be an Alpha tester, who helps to find and debug all problems which may appear. :) First of all Alpha may have a lot of bugs which should be fixed in future Beta and RC vesions. At the second 3d party modules should be updated but their vendors should have time to do it.

So, we've started to work with our modules since the first UNA 13 was relesed. We'll work with them one by one and all of them are updated till the final release of UNA 13.

Thanks for your report!
