  • This is a meaningless question for Stack Exchange. You don't mention what shield, and you haven't posted any code (that will survive if Pastebin goes down. I'm closing it as not a real question. – Nick Gammon Jan 22 '17 at 7:44

You are lacking a space:

client.println((String)"GET /msg.php?action=send&ID=2&message=" += currentMessage += "HTTP/1.1");

Your HTTP is running in to the content of your message ending up with a corrupt request. Also you are doing appending within your strings (+=) when you don't need to (+ is all that is needed). In fact, you don't even need that - just do multiple prints and reduce the hammering your heap is getting. Oh, and don't forget to use F():

client.print(F("GET /msg.php?action=send&ID=2&message="));
client.println(F(" HTTP/1.1"));
