I had the same problem so I checked the debug.log and I got:
PHP Fatal error: Unparenthesized
a ? b : c ? d : eis not supported. Use either
(a ? b : c) ? d : eor
a ? b : (c ? d : e)in wordpress/wp-content/plugins/sermon-manager-for-wordpress/views/wpfc-podcast-feed.php on line 165
So I added parentheses in line 165 so it looks like this:
'terms' => is_numeric( $terms ) ? intval( $terms ) : (false !== strpos( $terms, ',' ) ? array_map( 'sanitize_title', explode( ',', $terms ) ) : sanitize_title( $terms )),
This fixed the error for me.
Hope this helps.
