[solved] Uploads module error array_to_hash

[dango]

I'm helpless. I tried different ways (as recommended above) to show downloadable files. The result is always the same: Nothing ist displayed as content. Unfortunately I don't get an error message. Am I the only one, who cannot figure out, how to show downloadable files? The files are in the correct directore Uploads/"category". Could there be something wrong with access rights? Who can I figure that out? Thanx for any help.
