So I have both the field enabled for search and I checked the database and indeed there are images with the owner set to "paul", yet the search URL above does not yield any hits. Results are returned when using the Search field. Although I have other owners, "mike" for example that the Search field does not find any results for, even though it should. Could this be a problem with the theme? I noticed that when I use the Search field to search for owner=paul, I get a result set, but when I click on a result, I get the dreaded "Fatal error: Cannot access protected property SearchEngine::$dynalbumname ...".
