I’ve been using RoundCube webmail for the past 2 months on several different accounts with multiple installations. About a week ago I started getting a 500 Internal Server Error whenever I try to access it on any of the accounts, even though I hadn’t changed anything.
I wrote support and asked them if they upgraded or made and changes to any of the server software and they said no. Here’s what is showing up in my error log:
[Thu Feb 2 11:25:22 2006] [error] [client xxxxxxxxx] Premature end of script headers: /dh/cgi-system/php5.cgi
Can anybody tell me how to get it running again?
