I'm trying to add some new folders for my client in roundcube. But everytime when I try this I get an error: An error occured while saving I also cant delete any mails. But I read somewhere that I need to add the trash can. Also it doesnt add the sent folder when I send an email through roundcube. But the emails do get sended. I had this problem with roundcube 0.1 and I just updated to 2.1beta and I still have the same problems. Also my logs doesnt display any errors.
