The only reported issue thus far stems from how Jelsoft changed the vB pagenav, pagenav_pagelink, and pagenav_pagelinkrel templates for vB 3.6.6 and
this change has broken the PhotoPlog pagination when # is used in a PhotoPlog pagination link.
However, there is a workaround for the lite version
here, and for the pro version, there is a thread
here (accessible after purchase) that addresses the issue.
