I have problems with Debian Squeeze/ISPConfig 18.104.22.168 and Roundcube mail client. Sending and receiving works fine, but I can't change my password, set e-mail forwarding (from RoundCube, ISPConfig mail fw works). I tried a few things I've found online for this problem, but really can't step off "Soap Error: Error Fetching http headers". I do not have certificate for SSL. I've found this: Q: I get an error "Soap Error: fetching http headers" A: This happens when the plugins are trying to reach your interface under http but you have it run it under https. So just change it in the config file. Tried to play with force https variables (true/false), no luck. Any ideas?
