When editing a page as an admin in the ExhibitBuilder plugin, when I click on "Attach an Item", a new window pops up with a list of items to choose from. Within this window there is a "Search Form" button for searching and filtering items. However, this search form has no effect on the items shown; i.e. even after entering a search phrase the items are not filtered. I'm pretty sure this error is specific to something in my project and is not a problem with the ExhibitBuilder plugin.
Any ideas as to what could be causing the search form not to work?
