Individual blog post are not shown due to
error in sql query caused by a "space" char that is missing.

here is a quick fix:
open file : mod/oublog/locallib.php
inside function: oublog_get_posts()

change line:
$sqlwhere = " bi.oublogid = $oublog->id";

to:
$sqlwhere = " bi.oublogid = $oublog->id ";

(missing space char after the id)

btw. great blog module!!!
