Today I have installed the version 2.7, replacing 2.6.8 which I have been using.
I used your Copy to Pro plugin to migrate the data so that it was available in the new plugin. Though the files are now available, the Category information for each was lost.
I have re-applied the proper Category for each file, but even so the category shortcodes are no longer returning data. All I get is the toolbar, with no files appearing even though files are once again assigned to that category.
Is there something more I should do?
