Thanks for your  answer, it definitely seems to have pinpointed the  
problem. I created a session.d directory, and set the  
session_save_path as you proposed, and it seems to have solved the  
problem. (However, I had to create the directory manually, since the  
mkdirp-command generated an error message, but that was no serious  
problem).

When I searched the web for the solution to this issue, prior to  
mailing the list, I found several sites that displayed the very same  
error message. Might it be a good thing to include this solution in  
the sample-config as a commented out line? Even if it is not the  
fault of the pmWiki, I think it would be a great help, since it seems  
to happen occasionally, and it is a tricky error to debug.

Thanks again,
