Cant create node from users different than the app owner

Hi, I have my facebook account associated to my drupal admin account.
my facebook account holds the App ID i use for both facebook-connect and fb-photosync
Apparently earlier in the day, I managed to create content that was then sent to facebook from any user that had the permissions to create the node.
after playing around abit (trying to add tokens to the image description) things became a mess, but i have managed to get over the problems, except for one thing: the only one who can successfully create the nodes is the adminisitrator.
when a regular drupal user tries, I get:
The website encountered an unexpected error. Please try again later.

when a user that's account is "attached" to its facebook user tries, i get:
FacebookApiException: (#120) Invalid album id.
or
the 100# error, depends if the album is already created or not, i think.

how can i fix it? i want every user to be able to upload that content.

thanks alot :P
