Hello - i'm having this same issue.
i have joomla 2.5.2 VM 2.0.2 and the latest gavick esport tempalte 2.7 and the latest news_pro_gk4 3.0.3
My website is in full russian as default language - VM only lang is Russian - yet i still get VirtueMart is not installed or any VirtueMart categories are available.
I have 4 categories.. the funny thing is that i udated the module and thats when it stopped working.. if i don't save (
http://aleksandrshevchenko.org/store) the module it will work, however, if i want to make a change in the module settings - i will get "Error: No articles to display" after applying the changed. Obviously i already noticed that it said can't find the categories so i didn't save. However, i need to make some changes and this is no way around it of just not editing it.
What is the solution.
i've looked all over for the solution. Can't find one. I really need help. Can some one take a look at my site please and see what am i doing wrong.. however, it feels like it's a bug of some sort.
