I am using Joomla 1.7.3 and K2 v2.5.4. I am unable to get the pagebreak to work, all it does is display a horizontal line between the pages. I also installed UberPagebreak to see if this would work - it did not make any difference even after I unpublished teh Joomla pagebreak plug in. I have had to resort to making extra menu options for each page - uhh!! I must be doing something wrong, can anyone advise - many thanks.
PS An example is located here dev8.test-your-site.info/bodywork.html

I had a similar problem long time ago. As I remember it was something to do with other 3-party plugins to do. Try to unpublish them or put UberPagebreak at the the top of them.

Thanks for the advise. I unpublished all 3rd party plugins except k2 and still no joy.

I am having this same problem, can someone confirm that page break with with Joomla 1.7 and K2.
