Can't remove button after inserting into php code

Hi there,

Having an issue removing the Twitter button from my page. I added in the php code to my header.php, but then when I saw it was in the wrong place, deleted it and moved it elsewhere in the same template file, but it didn’t move it, instead it just added another one.

Now, I’ve deleted all php relating to the twitter plugin but the buttons remain – can you help?

Thanks in advance.
