Change head of web app

I create web app and distribute it for self hosting.
I try to change header of site like my personal name of site, but automated look header of site as “AppGyver”.
Please help me change name of site in header, and how I can create footer site in web app?

Best regards,

Its a bug. Vote on it on the tracker and maybe it will get fixed sooner.

EDIT: This doesn´t work …“As an interim workaround, edit the html files. Replace every Title tag with your apps name.”
