I'm seeing funny characters or boxes on my website after upgrading / moving to a new server. How do I fix it?

If you have any special characters in your html code, like », or ®, you need to make sure Apache is configured with the proper character set. Some symptoms are that you see little empty boxes or question marks, representing the characters that should be there.  If you look at your apache config file (httpd.conf), you might need this line:

AddDefaultCharset ISO-8859-1
