[pmwiki-users] session_write_close messages - Solved, I think

[Kevin Hayes]

When I put $EnableDiag=1; in config.php, the messages don't appear.
I'm still curious about this, as I think my host may have made some
changes to PHP that caused this and another spate of error messages
this week.

Otherwise, PmWiki is rock-solid as usual.
