I'm new en do have a for me big problem.
Roundcube works for me very, very well and that with my personal addressbook.
Because I like tot mail to my forum members via roundcube, I have to add groups, for example members A-H. I do get a popup for filling in the words, but when I like to save I get, "An error occurred while saving." And is it impossible to make that or any group.
My host uses the version Roundcube Webmail 1.1.0
I hop some one can help me.
If you using your hosts install of Roundcube you should contact them for support.
