When I try to open a user to modify data the screen remains blank and I get the following error message:

<blockquote>

Unknown column 'span' in 'where clause' SQL=SELECT a.* FROM jos_jsn_users AS a WHERE a.id = 3</blockquote>

As the error contains a reference to jsn_users, I think this is a good place to post this.

This afternoon I manually modified the users with last and first name and anew Easy Profile field and avatars.
The article I did build works well, all data are OK.
There are one or two fields I need to adapt, but that is impossible now.

Thanks Hugo
