XF 2.3 (Normal) User edit requires PW

[torstendlp]

Hi,

I want to edit normal users through the backend of my forum but always get the overlay error that I need to enter a correct password to do so.
But there is no field for my Admin PW anywhere.

I know thats its needed it I wanted to edit (Super)admins, but I only try to edit normal users.
I also - like someone said in another thread about the same problem on XF 2.2 - tried different browsers but that didn't help.

Any ideas?

Thank you

Torsten
