[pmwiki-users] problem editing after setting $DefaultPasswords['edit']

[gilbert n]

Sorry if this has been already  asked.
As I did not find any answer that could help me, I'm posting this message.
I'm very new to pmwiki
I have managed to set it up and start a nice pmwiki :) !

but when I have set the DefaultPassword like this for edit :

$DefaultPasswords['edit'] = '$1$hMMhCdfT$mZSCh.BJOidMRn4SOUUSi1';

(yes I have encrypt my password)

I can go thru it well when I want to edit, but my edition is not saved and I
have the following message each time after entering my password.


Warning: session_write_close() [function.session-write-close]:

what did I do wrong or forget ??
everything is OK if I only set the $DefaultPasswords['admin']

thank you very very much for your help, as now the only way to edit is to
leave my wiki without edit password (so anyone can do it !!)

all the best,

gilbert
