 * Hi Silvo: I tried updating Related Posts today. Not only do I have to activate
   it manually now, after I did so, WordPress came back with this:
 * > Fatal error: Cannot redeclare wp_related_posts() (previously declared in /vol/
   > jackyan.com/public_html/blog/wp-content/plugins/efficient-related-posts/efficient-
   > related-posts.php:607) in /vol/jackyan.com/public_html/blog/wp-content/plugins/
   > related-posts/compatibility.php on line 57
 * Can you let me know how this might be fixed? I really like this plug-in and had
   to abandon it on another website when it stopped working there (and replaced 
   it with something less accurate). I am on the latest version of WordPress.
 * Best regards,
 * Jack

 * I figured it out, Silvo, sorry. I had another related posts’ plug-in and there
   was a PHP conflict. Sorry to have bothered you.

 * Hey Jack, no need to apologize for anything, I’m glad you figured it out yourself!
   🙂
 * But do let me know if you stumble upon any problems in the future (hope not, 
   though!) — I’ll gladly offer you my help!
 * Take care!
 * Best,
    Silvo
