Several users have reported that the browse button and upload field are missing in the media manager.
I cannot reproduce it, but I can confirm it from seeing the screen captures they sent. I got one user to log out, clear the browser cache and log in again and that appeared to fix it, but only for a short time.
I've checked the user ACL lists and cannot see anything out of the ordinary.
Background: this wiki has been active for more than 3 years. I did an upgrade a week ago to the 2009-02-14 release by creating a new installation, copying the data across and then updating the index. Everything else has been working fine except the discussion plug (which adds 200+ identical comments each time instead of 1).
We think we have found a solution. We were using the ACL file from a previous installation.
The file (and the documentation) say that 16 is the highest level access (delete),
but there are now 5 permission levels and not 4. 1 + 2 + 4 + 8 + 16 = 31. We increased
the value to 31 and it works OK for users (admin now has no access to a couple of
namespaces but I can work round that). Can you please confirm this and, if necessary,
update the documentation?
Highest permission *is* 16. ACL levels *are not* bit fields. Higher permissions include lower permissions.
