Re: [pmwiki-users] pmwiki and 'user' php session handler (sharedanced)

Well.
 After some investigations, I found this error in the log : "Fatal
error: session_start(): Failed to initialize storage module: user".
Calling session_start twice when working with 'user'  set_save_handler
seems to have bad effect.

I patched my pmwiki.php (2.2.0 beta 42) with the following :

and now it works. Patrick : do you see any bad effect with this patch ?
