A list used in the SharePoint is given some unique permissions. Most of the users have the Contribute right and therefor should be able to view, add and edit items. That is what I want. But users can only add items, viewing and editing is not possible (event not if they try to view their own entries). I searched the web somehow, but I always only found the reverse problem, that people cannot add entries.
The advanced settings page contains an entry "Item-level Permissions". This is set to "Read access: Read all items". The user with whom I tested has definitely the Contribute permission (I used "Check Permissions" to validate it).
Me, as a Full Control user, can view everything. I thought of a column that maybe needs special rights, but I don't think so.
