Hi, i cannot run the K2 plugin on my template, what can I check to simply solve that problem, or what do you need to check it?

Cheers,

I cannot see the reason why you cannot install K2 on your template.
What errors are you getting?

I dont get any errors. K2 Module didnt appear on homepage, it has already <jdoc:include type="modules" name="artykuly" /> and same in templateDetails. In dashboard i've choosen pages with K2 and i select position of module in module manager.. And nothing ;/

Are other modules working in that position?
Also make sure that the K2 Content has content to display.
If you accidentally changed its settings and it can't find items that match your criteria, then the module will not render.
