There is a severe bug in the pagination feature which occurs whenever you have multiple WPDM short codes on a single WP page.
I have multiple WP posts items, each having a WPDM package short code embedded like this
[wpdm_all_packages thumb=1 items_per_page="5" categories="mycategory" jstable=0
order_by="field_name" order="ASC/DESC"
cols="thumb|title|post_content|file_size|publish_date|download_link"
colheads="|Title|Description|Size|Published||"]
As soon as I embed more than one WPDM post in a single page (using WP plugin, short code [insert page=”post#” display=”content”) the pagination doesn’t work properly. For example, clicking on / selecting page 2 switches all doenload listings to page 2, not only the one you clicked on. This said, the URL parameter “?cp=2” applies for all [wpdm_all_packages] download lists.
