I have a phpBB3 account (http://hogwartsamerica.50.forumer.com)

I have attempted both uploading and linking to a URL for a different site logo, but it will not accept my changes. I can only use the existing images in the skin set or none at all.

When attempting to upload, I get an error that the file is either the wrong extension, too large or an invalid file type. I know that none of these apply.

When I attempt to link a URL, it shows the chosen image under "CHOSEN IMAGE:" but "SELECTED IMAGE" shows a blank.

EXISTING CUSTOM IMAGE can only be set to NO - I'm assuming this is because I cannot upload images.

Here is a screenshot: FYI - the image is a spoof that I made some time ago - the label says "I Can't Believe It's Not BUTTERBEER. Harry Potter fans will get the joke.

I have also attempted to edit the style sheet, but the site logo is not defined there. I viewed the page source of my index page, and the site logo image is declared THERE, in the body of the document in a DIV tag with the id "header". it is very frustrating that I now know WHERE the change needs to occur, but do not know how to effect that change.
