Integration ispconfig - roundcube 1.0 no more work ?

I have the same problem like you. Is strange because this is 3th server and second time when this problem occur. So, i have 2 server working fine. Same settings, no problem. On the second server this problem appeared but i says: the problem is me because i want to install roundcube 1.4 instead 1.3 like in tutorial.
So I reinstalled entire server, step by step and everything was fine.
Now the problem reappeared and I don't see any problem in apache log. I don't know where is the point to start debug. I don't want to reinstall entire server
EDITED!!!
PROBLEM SOLVED:
It was my mistake.
In /opt/roundcube/plugins/ispconfig3_account/config/config.inc.php
It was write http instead https.
In my case https is correct mode.
$rcmail_config['soap_url'] = 'https://myserver: port/remote/'

<?php
$rcmail_config['identity_limit'] = false;
$rcmail_config['remote_soap_user'] = 'remote user';
$rcmail_config['remote_soap_pass'] = 'remote user password';
$rcmail_config['soap_url'] = 'https://myserver : port/remote/';
?>

Thank You Till for your tutorials!

 

Hello,
I have a problem with roundcube_0.7.2-9+deb7u8 and ispconfig 3.1.6. My sistem is Debian GNU/Linux 7.11 (wheezy) with Apache/2.2.22 (Debian), PHP 5.4.45-0+deb7u10 , postfix 2.9.6, dovecot 2.1.7, IspConfig 3.1.6.
I installed and reinstall roundcube_0.7.2-9+deb7u8_all.deb from the tutorial (https://www.howtoforge.com/using-roundcube-webmail-with-ispconfig-3-on-debian-wheezy-apache2) and I can't solve it.
I'm going to log in myhost/webmail/ with my user and password and it works, but, when I access the settings (myhost/webmail/?_task=settings) menu in webmail I get ERROR 500.
from logs single error is:
[30-Aug-2017 10:07:33 Europe/Bucharest] PHP Fatal error: Class 'rcube' not found in /var/lib/roundcube/plugins/ispconfig3_account/ispconfig3_account.php on line 12
What can i do to resolve this issue ?
Please Help.
Thank you !

 

Is Your question about https://github.com/w2c/ispconfig3_roundcube ? If yes, the latest version of that does not work with the roundcube in Debian Wheezy. I got the plugin working by guessing which version still worked with Wheezy roundcube and installing that.
