I just ran into a similar problem after installing the Feedburner Feedsmith plugin into my WordPress 2.7.1 installation at musicgoondu.com. After installation, I got the following error at the top of every page including WP Admin:
Warning: include_once(/home/themuser/public_html/musicgoondu/wp-content/plugins/__MACOSX/) [function.include-once]: failed to open stream: Success in /home/themuser/public_html/musicgoondu/wp-settings.php on line 473
Warning: include_once() [function.include]: Failed opening ‘/home/themuser/public_html/musicgoondu/wp-content/plugins/__MACOSX/’ for inclusion (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/themuser/public_html/musicgoondu/wp-settings.php on line 473
I deactivated the plugin, with no improvement, so I deleted it. Then I proceeded to deactivate all my other active plugins. Still no luck. Any suggestions would much appreciated.
Thanks,
Chris
