I tried this - [button class="green" url="/"]Press[/button]
and it also got stripped out.
I made the change referred to in the other topic, although I didn't find that code on line 231, I found it at line 247.
Sure - attached is a screenshot of where I am trying to place a shortcode. It actually seems to get stripped out upon saving because if I go back into edit the Album after saving it, the shortcode has disappeared. Thanks!
That is the thread I already referred to - it shows how to put a shortcode in the ALBUM description field, but I need to put it in in the PHOTO description field - so the code referred to in the link above doesn't work for this.
