Hi,
I install the interior template in a new joomla 3.4.8 and try to change style from default to preinstalled dark-menu.
I use the warp customizer.
But it wouldn´t save. Always, if I enter the customizer again it changed to the default and the page didn´t changed anything.

Can anybody help?

Hi there,
1.) Never edit the original styles!
2.) Customizer > Copy > Your new style name
3.) Now edit your new style and save
4.) Select your created style as default in Template options > Layout > Style ( see image attached)



PS: Please delete all layouts you dont need!

Problem solved.
