I will test the problem with default skins. DNN 4.4 still has a lot of bugs and there are some problems I will be addressing in a near version.
About the option to move DSLocalizator to Admin. It is another DNN bug. The routine that creates the module tells the system tu create the module with a cache of 0, and DNN is not taking it into consideration and puts a -1 as a value, then DNN is not validating this value and not showing the module
A workaround is to change the cachetime from -1 to 0 and restart the application. The table is tabmodules
You will se that there is no other -1 value than the one for the localizator module
I will try to find a solution and release a new version as soon as I can.
I will need more testing on 4.4 (Version 2.0 of DSLocalizator will work only on DNN 4.x and will address this new issues better). At this time the module is compatible most versions.
