Pour etre sur que ca ne vient pas de la config apache, g force la variable $tmpl_dir :
Code:
my $tmpl_dir = "/home/iifiir/cgi-bin/";
et ds ce cas la, j'ai plus le meme message d'erreur, mais plutot : Internal server error: et ds le log error: Premature end of script headers: /home/iifiir/cgi-bin/email.pl

ca fait plus d'un mois que cela dur... :cry:

merci encore une fois pour ton aide
