Hello Jan, I have made some fixes in X2GoPlugin code for several minutes: http://code.x2go.org/gitweb?p=x2goclient.git;a=commit;h=d4d0fe38610d3e514dc2e4e259ce8f103e4ac535 Please test it. The documentation in our wiki about X2Go Plugin configuration was too old. Since we using qtbrowserplugin for building X2Go Plugin we don't need a configuration file any more. All settings should be saved direct in HTML-File. I have the wiki page also updated, please check it:
