I have a problem when I try to use https on my webmail site. (roundcube)
Also there is the same problem if I try to use the ISPConfig WebGUI via https.
Since last week I get the following error
Your browser sent a request that this server could not understand.
Request header field is missing ':' separator.
,but everytime with a different error code in the last section.
If I reload the page long enough I get to the login screen and further, but than after some time I get the error again.
here is the log for the error
[17/Sep/2011:14:11:45 +0200] "GET / HTTP/1.1" 400 232 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2"
If I disable https in the apache2 config file (for ISPConfig), or disable https in the WebGUI for my webmail site, everything works fine.
I already tried different browser, but the error was still the same.
I would like to use https again, but with this error I can't
Thanks for your help.
