Query failed: ERROR - Open an Article
When I click on an article to see more information about it, I have the following error/warning:
Warning: pg_query() [function.pg-query]: Query failed: ERROR: column "documents.extension" must appear in the GROUP BY clause or be used in an aggregate function in /mysite/spip/ecrire/req/pg.php on line 147
I'm using [[PostgreSQL]] 8.3.
Thanks
