When I make a new 'Gallery' content type and a new 'Gallery Item' content type and link them in a Gallery Relationship the 'Upload New Items' button of the standard Gallery and Gallery Item Relation disappears. Then I tried to put in the url [website]/node/[number]/upload, that should be the url for uploading new images in a gallery I get the error: You are not authorized to access this page. I have full permissions and I edit the website with the first user. How could this happen? I really like to know if anyone knows the awnser!

The list of enabled modules:
ctools-7.x-1.3
entity-7.x-1.1
entityreference-7.x-1.0
file_entity-7.x-2.0-unstable7
libraries-7.x-2.1
plupload-7.x-1.1
views-7.x-3.7
views_slideshow-7.x-3.0

I don't know, but maybe this is related to the error i described here: http://drupal.org/node/1977556
