 * hi. Hope you can help! I installed a plugin from seologs.com (the “blogthis” 
   plugin). But ever since my blog is a mess, particularlyt the header. I’m not 
   getting this message:
 * Warning: include_once(/home/janbanis/public_html/easyonlinebusinessinfo/wp-content/
   plugins/__MACOSX/) [function.include-once]: failed to open stream: Success in/
   home/janbanis/public_html/easyonlinebusinessinfo/wp-settings.php on line 473
 * Warning: include_once() [function.include]: Failed opening ‘/home/janbanis/public_html/
   easyonlinebusinessinfo/wp-content/plugins/__MACOSX/’ for inclusion (include_path
   =’.:/usr/lib/php:/usr/local/lib/php’) in /home/janbanis/public_html/easyonlinebusinessinfo/
   wp-settings.php on line 473
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/janbanis/public_html/easyonlinebusinessinfo/wp-settings.php:473) in /

 * The plugin was installed using the installation feature in wordpress 2.7, so 
   it was installed directly from the zipfile on my desktop. However, when I checked
   the plugin folder in my ftp client, i noticed that some folder called _MACOSX
   was also installed/copied. Anyway I deleted the lots, which may be the reason
   why the last 2 error messages dont have a reference to that folder in it.
 * I know nothing about php and just want to rectify this as soon as possible. Thanks
   so much for any help.
 * Jan
