Right, I've gone through all the settings my experience can allow me to figure out, but I guess I'm missing something obvious.
I have a server at the moment wich is behaving weirdly with RoundCube.
It has several domains and it's all set up nicely and works for all domains except one. The last one constantly timeout at login and leaves me with an empty screen (
http://webmail.domain.se/?_task=mail).
Now I'm not sure, but I don't think it's a RoundCube issue? Since it just behaves like this on one domain. Checking the settings on all domains shows that they are the same as the faulty one.
Other then that, it works like a charm on the rest of the domains, with no hiccups at all.
