Hi,

I have installed and enabled og_forum and when a group member tries to create a forum topic above the forum topic creation form below error displayed;

* warning: pg_query() [function.pg-query]: Query failed: ERROR: invalid input syntax for integer: " .14. " in /www/htdocs/agora/includes/database.pgsql.inc on line 139.
* user warning: query: SELECT t.* FROM term_node r INNER JOIN (SELECT DISTINCT ON (tid) * FROM term_data) t ON r.tid = t.tid INNER JOIN vocabulary v ON t.vid = v.vid LEFT JOIN og_term ogt ON t.tid = ogt.tid WHERE (t.tid NOT IN (SELECT x.tid FROM (SELECT DISTINCT(ogt.tid) FROM og_term ogt INNER JOIN og_uid ogu ON ogt.nid = ogu.nid AND ogu.uid != ' .14. ') x WHERE x.tid NOT IN (SELECT DISTINCT(ogt.tid) FROM og_term ogt INNER JOIN og_uid ogu ON ogt.nid = ogu.nid AND ogu.uid = ' .14. ')) AND ogt.nid = 1) AND ( r.vid = 1 )ORDER BY v.weight, t.weight, t.name in /www/htdocs/agora/modules/taxonomy/taxonomy.module on line 618.

How can I solve that issue?
By the way new forum topic is created.
