PHP Fatal error with Audio update
Using Jamroom
Adding a audio_description field as an 'editor' field works. When I open the CREATE form or the UPDATE form for an audio item I do not see the same error as you.
What are the steps to get to the page where that error shows? or what is the URL of the page where the error shows.
My guess is the issue is that some other module is causing problems, not the editor form field.
