I have installed Joomla RT Quantive Launcher including sample data on a local computer. I have then installed Crystalline as a standalone template and made it default at the backend template manager.
The results before/after are attached.
What I understand is that it is not enough as before to change the template at the backend and make module position modifications.
Images won't show, Roknavmenu won't sometimes work. Roknewspager won't work. Some modules are not well-aligned.
There are more to be done but don't know what.
