adding to the lsr isn't working

[chip]

I have finally go registered to add my template to the LSR and have 
added all the relevant info into the form to do so. When I click on 
either the Go button or the Save button I get a pop-up box that says -

The page at https://lsr.dsi.unumi.it says:
No output from Lilypond

I have tried several times but it just won't work.

What am I doing wrong?
