 * Be aware that if you happen to be using the markdown plugin, it will cause all
   kinds of funkiness with displaying posts. Titles and dates will show up, but 
   the body of each post will show up blank. According to the error log, any attempt
   to bring up a post would throw the following error:
 * [Mon Dec 19 23:39:08 2005] [error] [client 71.x.x.x] PHP Warning: preg_replace_callback()[
   [function.preg-replace-callback](https://wordpress.org/support/topic/php-511/function.preg-replace-callback?output_format=md)]:
   Unknown modifier ‘|’ in {$worpress_directory}\\wp-content\\plugins\\markdown.
   php on line 827
 * This on a machine running Apache 2.0.55, Windows XP OS. Running the 1.5.2 Strayhorn
   package. Deactivating the mardown plugin seems to resolve the issue.
