I had the same problem so I was just disabled the lines 193 and 194.

From:
$isphp = false !== strpos($r[‘feed_permalink’],’.php’,
strlen($r[‘feed_permalink’]) – 4);

To:
//$isphp = false !== strpos($r[‘feed_permalink’],’.php’,
//strlen($r[‘feed_permalink’]) – 4);

Now the SexyBookmarks seems to work well.

Anyone have a better solution?

You can use this plugin:

Then go to the ‘Permalink’ and set the ‘Custom Structure’ to the HTML file name you want.
