[MorrisJobke]

• password form overlaps upload button and doesn't allow to click it
• regression from allow admin to disable groups on personal page #5259

When you disable password change (hack if($_['passwordChangeSupported']) in the template), the problem continues with the language drop down blocking the name and email field:

I pushed a update which should always work. Not sure if it is the most elegant solution, though.

@MorrisJobke feel free to replace it if you know a better way to solve it.

Thanks @schiessle - I condensed the CSS rules and squashed everything.
