[solved] Ispconfig 188.8.131.52 upgrade : Quota and SSL Hello, I upgraded ISPConfig from 184.108.40.206 to 220.127.116.11 today with the shell upgrade script, all run correctly and upgrade was successfull. Since the upgrade, all sites where defined previously with traffic quota to 0 (no restriction) under 18.104.22.168. Now with the new version of ISPConfig, the control panel complain that traffic quota is set to 0 and I could not change settings of site before changing the traffic quota value (I enter -1 as for disk quota). Is it normal that traffic quota can't be set to 0 for unlimited traffic ? I have only one public ip as I use only one server until now, so all my vhosts use the same ip. Does anyone know a solution that will allow to use ssl connection for access to ISPConfig control panel, and vhosts ? UPDATE : My problem is solved for quota management. Moreover, for roundcube 0.3.1 if you encounter problem for login user with imap server add the following apache directive "php_admin_value mbstring.func_overload 0" to your site definition and it should be allright.
