RounCube-0.2 alpha has been released. From RoundCube 0.2 and up, the php modules/extensions PCRE, Session and DOM XML are required. The last one (DOM-XML) does not come with ISPConfig on the moment. To continue the maintenance of the RoundCube package for ISPConfig, i ask you to give support for DOM-XML with the next version of ISPConfig. I will provide the new RoundCube package for ISPConfig on the moment that ISPConfig will suport DOM-XML. Thanks in advance!
