Once again - one more problems with this plugin.
As described in the Title, the "ad media" button isn´t working anymore, you can choose the gallery and all of the pictures, the attemp fails and the blank media-window isn´t closing. The server logs shows folling error:
PHP Fatal error: Call to a member function id() on a non-object in ... /nextgen-gallery/products/photocrati_nextgen/modules/nextgen_gallery_display/class.display_type_controller.php on line 210, referer: .../wp-admin/media-upload.php?type=file&tab=nextgen&chromeless=1&post_id=1638&select_gal=16
The above mentioned lines in class.display_type_controller.php stats: "Returns the effect HTML code for the displayed gallery and param type $displayed_gallery"
