I have got a header for my website but i have added the wrong name on it how do i go about changing it,

 

for some reason if i try typing over it it just goes over

 

if anyone can help me or point me in right direction

 

thanks

Sorry, you'll have to give us a bit more information than that. What is the header? Is it an image? If it's an image then you will need to use an editing program like photoshop to change the graphic and then re-upload it. If it's just html, then you should be able to change the text using your cms or html editor.
