Ah – now I understand what you meant. I hadn’t even thought about fixing it at the Airtable end.
Anyway – I think I fixed it with a little PHP in WordPress
function decode_request($req){
$req->request=urldecode($req->request);
return $req;
}
add_action( 'parse_request',"decode_request",1,1);
thanks for your ideas though – it’s good to have options.
