 * I’m getting a strange error after installing your plugin:
 * > Notice: Undefined property: stdClass::$errors in /home/r25/public_html/wp-content/
   > plugins/tweet-old-post/inc/core.php on line 304
   > Notice: Trying to get property of non-object in /home/r25/public_html/wp-content/
   > plugins/tweet-old-post/inc/core.php on line 304
   >  Congrats! Your last post was
   > revived successfully
 * What can I do about this?

 * I’d forgotten I had WP-DEBUG set to true in wp-config, when I turned it off, 
   the message stopped appearing. Still, it seems to indicate something wrong with
   Revive Old Post coding…

 * Any idea what would cause it on certain sites? “Undefined property” – perhaps
   some sites don’t have the “property” you’re referring to there?

 * Might be an issue in some conditions, I will take a deeper look. However is not
   a big thing, so should not affect your experience.
