Hi!
I was using roundcube 0.2.2-stable from Debian Lenny package and wanted upgrade to 0.3-stable, but that package for Debian do not exist yet. So I purged all data, program and database to start cleanly. Then I installed 0.3 step by step, and system works fine. Tried few plugins, most of them worked. Anyway, everything is OK when I use the "default" skin. But in version 0.2.2 I have skins "air" and "umich" which are both very nice. However, now when I applied them, I get nasty error: "SERVICE CURRENTLY NOT AVAILABLE", with ERROR 501. I do "logout" and "login", most parts of themes are applied, but on page "Settings" 1st tab is empty, only with option "save" at the bottom. Tabs "Options" and "Identities" are OK. To remedy this situation, I must edit "roundcubemail" mysql database and delete all settings about theme on specific user which have this problem. In my installation map "installer" does not exist any more, as suggested by install tutorial, so I cannot fix that file "check.php". In "errors" log files nothing comes out (I mostly see only "authentication failed" for some users). Please, what could be wrong? For me, proper theme support is important as is plugins. Btw, my PHP version is 5.2.6.
