   A continuation from this post, a new bug was found with regards to the view external link button on the facebook app, when the permalink contains the app's name.

   Code in question:
   

   <?php
   // code to get the url of the orginal post for use in the "show external url view"
   //get the permalink
   $permalink_peices = parse_url(get_permalink());
   //get the app_url and the preceeding slash
   $permalink_app_url = "/".$app_url;
   //remove /appname
   $external_post_permalink = str_replace($permalink_app_url,"","$permalink_peices[path]");
   //re-write the post url using the site url
   $external_site_url_peices = parse_url(get_bloginfo('wpurl'));
   
   //break apart the external site address and get just the "site.com" part
   $external_site_url = $external_site_url_peices[host];
   $exteral_post_url = get_bloginfo('wpurl').$external_post_permalink;
   
   //echo external post url
   echo "<a href='$exteral_post_url' title='View this post on the web at $external_site_url'>View post on $external_site_url</a>";  ?>

   Brett,

   I think I found a solution to the issue. Add the following function either in you theme/index.php or (recommended) to the theme/config.php

   // check to see if external post link contains the app name and only replace the first instance use this function
   function str_replace_once($needle, $replace, $haystack) {
      // Looks for the first occurence of $needle in $haystack
      // and replaces it with $replace.
      $pos = strpos($haystack, $needle);
      if ($pos === false) {
          // Nothing found
          return $haystack;
      }
      return substr_replace($haystack, $replace, $pos, strlen($needle));
   }

   this function will only replace the first occurence of the variable.

   Next replace:
   

   $external_post_permalink = str_replace($permalink_app_url,"","$permalink_peices[path]");

   With:
   $external_post_permalink = str_replace_once($permalink_app_url,"",$permalink_peices[path]);

   On both lines 134 and 182

   This will hopefully make it into the next release but should fix your problem if you feel comfortable modifying the code a bit.
