First off, great plugin! Loving it so far.
My problem is, both the 'sortable' and 'read-only' columns don't work.
Or to be more specific: In the Participants List page (with [pdb_list]) nothing is sortable, even if it's checked.
The problem with the 'read-only' is on the Records Page (with [pdb_record]) - there seem to be some major interference because not only disappear the lines where I checked 'read-only', everything beneath them too - no Save button, no photo - not even the WordPress Toolbar displays which is on top of the screen if one is logged in. I'm guessing a CSS class interferes there.
I use the Pinboard theme, you can find it here: http://www.onedesigns.com/wordpress-themes/pinboard
