Hi.
I'm a K2 newbie and I'm starting discovering the K2 world. I created some k2 items with pagebreak (the standard Joomla pagebreak feature available in jce editor) but the pagebreaks do not work: they appear as a simple line in the article content.
I've searched on internet and found old articles about this issue suggesting the need of another external plugin called PageBreakMySpace in order to solve the problem.
Could someone tell me if there are other options to let the standard pagebreak work for K2 items?

I get the same results with latest joomla and k2 versions. with j articles the page break works
With k2 2.8 a line prints across the item when viewed
Switched to default prostar template and nothing changes

Hello Joomla!'s page break will not work in K2 items.
You will need a 3rd party extension, you can search in the JED for such an extension.
