Url2Commons not uploading files

[Former user]

The whole description available at: https://commons.wikimedia.org/w/index.php?title=Commons:Village_pump/Technical&oldid=542466846#Url2Commons:_simulation_OK,_upload_failed

I've tried to upload some files via [https://url2commons.toolforge.org/ url2commons], the simulation was OK, but the upload failed. I'm assuming that something can be wrong with the $DESCRIPTOR$ string, but I can't find out, what is causing the problems – there is no further error explanation. The hard-typed descriptions worked well.

After few days I tried the uploads without descriptions – just original filename and Commons filename:

http://bubenic.cz/fotky/2013/02_okolo_prilep/imgp7462.jpg Přílepy, imgp7462 (2013-02).jpg

but now it failed even without the pipeline followed by $DESCRIPTOR$. Url2Commons returned unknown "ERROR" and "X uploads failed" without other notice, the file isn't uploaded.
