OK - another gallery, different site, strange error...
Loaded up ss3Gallery, SortableGridField and GridFieldBulkEditingTools. Have the Image Gallery tab in the CMS, can go through to upload screens and Bulk Upload images -- however I am unable to set up a destination folder.
Image Gallery doesn't do this automatically, nor can I set up a folder and point to it.
The end result is I get a 'Not Found' error, combined with the message 'Please Wait... Upload in progress..." running in perpetuity.
Firebug tells me:
"NetworkError: 404 Not Found - http://localhost/SS-v3.1.3/index.php/admin/pages/edit/EditForm/field/GalleryImages/bulkimageupload/bulkImageUploadForm/field/BulkImageUploadField/fileexists?filename=Hackett.jpg"
Anybody else had this??
