Ok. I removed zz_faq by deleting lines in zz_aplication_top and some other files. The shop started with some errors. I installed Latest News 1.1 which was needed by your osc snaphot.
I still have some essential problems. I can`t force osc to show prices with discount, but strange, when I enter a discount (in admin in Localization/Customer Status) with minus sign (for egz. -10.00), I see the discount --10.00%. This means that the standard price is 10$ and with discount 11% - very interesting.
Another thing: In left panel I have error
and in right panel
Near the bottom I`ve got
I hope some help will do some progress also for others with instalation problems. :?
