[pmwiki-users] save buttons cause page to revert

[Karin Armstrong]

Hi -- I just installed an instance of pmwiki 2.1.5; I have another  
instance on the same server that works fine.  However, the new  
install won't let me edit.  Inside the edit pane, if I hit save, the  
edit pane remains and reverts to its prior state, losing all of the  
changes.

I have checked the wiki.d permissions, and set them to 777.  The  
config.php seems correct; I used the sample-config and went through  
the options.  Any suggestions on how to fix things?

Many thanks!
Karin
