Need help with “Miscellaneous Settings”

Hi,

I have a wordpress plugin setup to embed a specific filetype (.SGF).

When I upload the file through the plugin, I get this in my post:
(WordPress is installed in http://www.domain.com/articles/)
[sgf sgfUrl=”/wp-content/uploads/2010/04/example4.sgf” href=”http://www.allaboutgo.com/articles/wp-content/uploads/2010/04/example4.sgf” class=”aligncenter”][/sgf]

Notice how “sgfURL=”/…” which tells it to look in the root directory, not in the “/articles/” directory. I have tried changing the settings in “miscellaneous settings” but nothing worked. I think this is a problem with the plugin I am using. I looked at the code and found this:

# Figure out where we're really getting the SGF data from
		$sgfurl = $params['sgfurl'];
		if ($sgfurl) {
			if (substr($sgfurl, 0, strlen(WP_CONTENT_URL)) == WP_CONTENT_URL) {
				# absolute URL, but local
				$sgf_file = WP_CONTENT_DIR . substr($sgfurl, strlen(WP_CONTENT_URL));
			} elseif (preg_match('!https?://!', $sgfurl)) {
				# remote
				$sgf_file = '-';
				$sgf_data = file_get_contents($sgfurl, 0, null, -1, 65536);
			} elseif (substr($sgfurl, 0, 1) == '/') {
				# relative URL, local
				$sgf_file = ABSPATH . ltrim($sgfurl, '/');
			} else {
				# no idea
				return $fallback;
			}
		} else {
			# using sgf data
			$sgf_file = '-';
		}

I think the problem is in there, but I am really not sure what to change (and I don’t want to accidently break anything).

Can someone help me? I hope it is as simple as deleting a line from the above PHP code, but I don’t understand PHP well enough to know what that line is.

I can give more details if requested.

Thanks.
