Can't save changes made in user settings

Permalink
Hi,
i can edit a user but can't add an avatar nor save the changes i've made.
It says something like: 'A username can only contain ...'

Anyone has a clue?
Thanks very much, Mieke

it seems to be complaining about character usage in the username - what's the username?
Is it just a one-off or for any user you try to add?

Hi Andy,

ok, made a new user and found out there must be something like an underscore between First and Last name.
So now i can edit and save but still can't update an avatar. It stays on 'No file selected'

By the way, on the user search page i first got this message:
'Not able to get the key for access_user_search_export'
I (later on) fixed that by uncomment line 124-128 in search_results.php in concrete/elements/users but it had no influence on the avatar upload/save

A database or permission thing??

Thanks Andy for your help!
