I've just installed your calendar. Works fine and I've encountered no issue during installation (have to do it in /fr also <- that's maybe why)
but I've a little concern regarding colours, everything is plain dark blue
As I've seen on your demo site, I must have some grey, light blue,...
2 picts are better to explain :
I don't have a clue to where to look at. Everything seems to be like in install.xml and prosilver.xml
It doesn't seems to be linked to /en to /fr things and all the .css are up to date
I don't have any custom colours too.
Any ideas ?
ps : sorry for my quite poor english
