Fatal error

Hi all. I was showing a friend the views module on a site and I seem to have messed things up to a point where I haven't been able to recreate the view. The error I'm getting is:

Fatal error: Cannot access empty property in /home/content/40/4818240/html/sites/all/modules/ffpc/ffpc_plugin_row_podcast.inc on line 86

Oddly enough, a similar view that acts on the same data does not generate the error (OGG feed) (MP3 feed is broke).

Any ideas?

Dear Drupal experts,

We are a group of concerned individuals, that seek to help the worlds tribal peoples. We work to protect their human rights, environments and cultures. In Germany we are registered as an e. V. organisation (not-for-profit). See: www.naturvoelker.org but our interCultural site: www.fPcN-global.org is where we need to help. A volunteer, offering to upgrade from 4.7 to 5.5 got in to a real mess and was unable to complete the task in anything like a reasonable time, leaving us off line and with a disabled site for months.
