500 Internal Server Error when using .htaccess with RewriteEngine

.htaccess mod-rewrite

I am on the shared host Bounceweb and I am trying to add some rewrite rules to make my links look prettier.

One of these rules is to make the url: http://mysite.com/upload point to: http://mysite.com/upload.php. I have this in my .htaccess file:

RewriteEngine on
RewriteRule ^upload$ upload.php

but all it's giving me is a 500 Internal Server Error. I looked at my logs and this comes up a lot:

[alert] [client 81.179.29.185] /home/minecraf/public_html/.htaccess: Invalid command '\xef\xbb\xbfRewriteEngine', perhaps misspelled or defined by a module not included in the server configuration

Does this mean my host doesn't support .htaccess? Pretty lame if they don't. I've already tried changing the permissions of .htaccess to 777 and it doesn't help.

Thanks!

\xef\xbb\xbf are three invisible junk characters (at least from Apache's perspective) called the Unicode BOM, or byte order mark. Apache thinks that those characters are part of the command that follows right after. This is what you see in the log, though the characters are escaped so they're visible to the naked eye. \xef\xbb\xbfRewriteEngine

In your editor, especially if your editor is Notepad, make sure you're saving your file without a BOM. This should be selectable in the save as dialog or elsewhere.
