Hi!
Thank you so much for the details, it helps a lot!
The configuration seems to be correct, these items seem to be stored in the wpfd_file post type. However I have noticed that on the old version clicking on a datasheed leads to a page that works, however on the new one it doesn’t. For example:
– Old: https://old.sensysnetworks.com/wpfd_file/datasheet-flexcontrol-card-apcc-enclosure/
– New: https://sensysnetworks.com/wpfd_file/datasheet-flexcontrol-card-apcc-enclosure/
That means that these items are likely not published or does not exist in that post type anymore or there is some sort of a configuration difference inbetween the old version and the new site version in the file manager plugin. Once they are accessible they should automatically include them in the results.
