I am having this issue where there is no little + icon that would allow me to save a new “desktop”. I am also unable to save the current layout once I have made changes to it.
I tried using Chrome and Firefox.
Problem was due to entering a password in the password.php file (in root folder).
After blanking out the password field, problem was resolved.
Supplying a password in that file is only for recovery reasons.
After filling a password in that file, login in AudioStreamer and change (and save) your password.
And next step, you should clear the password field in the file.
