Others ⇒ WebQuiz compilation and html output file empty

[Feryal]

Hi
This is my first post on this forum.
I'm working on the WebQuiz package. I started with first example given by the reference document webquiz.pdf. After pdflatex compilation of my first example (Quiz-1.tex), I get the pdf output document and it's ok (as explained on WebQuiz.pdf reference). But when I made the webquiz compilation (webquiz Quiz-1.tex), I get the html output document but a little empty (see figure please, displayed by Safari). I checked on the Safari preferences and the Javascript is active.
I've any compilation errors.
Could'you please help me ? Thank you very much.
