Steps to reproduce
- Install owncloud to ubuntu server with http—s sertificate.
- Activate http–2 apache module
Expected behaviour
Server must run without problems
Actual behaviour
I will attach link with screen from errors panel in firstreply, Because this window doesnt allows me to attach links 
When i try to login webui with different browsers, behaviour can be various. And in each case there are several issues with UI display. Look info above.
Google chrome standard mode - no issues
Google chrome incognito mode - white background of UI (no image), cant login via web after entering login/pass combination and pushing enter. Also arrow in password input didn’t showed to user.
Look screens.
If i reboot page i can see interface - but also cant enter in admin panel. (Look screens)
In console tonns of errors 403/
Firefox - issues after login ( Forbidden You don’t have permission to access this resource.).
I can see web ui without problems and can login. But with many error of mime type (look screens)
After login i see many forbidden errors and no one link is working -> (look screens)
This all happens after i enabled http----2 mod on apache. If i manually activate http—1 mode - problems go out.
