All work fine but :
When i try to connect to my pgsql server I have this error :
Warning: Unable to connect to PostgresSQL server: ERROR: MultiByte strings (MB) must be enabled to use this function in toto.php<3-4> on line 40
The function is :
$conn =pg_connect("pgsql.euroconnect.fr","5432","","","toto");
I have the same error with php3 or php4 files

If somebody know a solution, it will be great.
Thank you very much for your help.

Best regards
