Two things you can try:
- Go to the address field of your browser and press enter, or press "Go". This should cause it to go to the script without the POST data, displaying the first page. Then, you can refresh if necessary.
- If that don't work, tack something like ?a=b (anything goes) to the end of the url, and try step 1. again. This should definetely make it into a GET instead of POST. A bit awkvard, but better than your current method.
These things usually works, but I confess I didn't try it on your script. Also, take up
io's advice on security. :)
Hope that helps.
