Hallo,
I installed roundcube rc1. Im unable to open, view oder download an attachment. I added a picture how it looks like when I open an attachment. It seems that a new tab is created with the raw data of the file ...
On the same server I'm using rc-beta2, there I've got no problems with attachment ...
I think this is a bug ...
Nico
