RSS Feed Not Working in 2.0.7

I guess it linked my period with the URL too.
Here is the URL again:

Your feed starts with blank line which breaks it.

Typically, that happens if a plugin (added any lately?) has extra whitespace or line feeds before the opening <?php or after the final closing ?>.

I haven’t added any lately… but I did disable them and found out which one was causing it…

Optimal Title. I have V2.0 (the latest).
Here is the website about it: https://elasticdog.com/2004/09/optimal-title/

What do I need to edit to fix this? Do I have to ditch Optimal Title? I really like how it sticks the post name in front, rather than getting the breadcrum path to it.

Perhaps I should give you what is inside my header.php title tag…
<?php optimal_title(); ?><?php bloginfo('name'); ?><?php if ( is_single() ) { ?> &raquo; Blog Archive <?php } ?>

open up the plugin file with a text editor.

Any blank lines at the very top or very end? If so, delete ’em.

That was it ??
I didn’t realize blank lines AFTER all the php statements would cause any problems, but it did have 3 lines of nothing at the end of the file.

Thanks!
