Somewhere along the line my module using the Portfolio II setting has broken.
I went back a couple of months in my backups to see if I could find a working version and I found that under 1.6.3 of the J3 version, the module is working fine.
When I update to the latest version of NSP 1.7.1, it no longer loads any content in the module. Same for Portfolio setting. The other settings seem to all be working.
I was looking for other interim versions between 1.6.3 to 1.7.1 to test out to see exactly which version broke it, but I couldn't find anything.
How can I get it working again?
