Yet Another Related Post Plugin (YARPP) was just recently updated (March 3, 2012) and it calls a fatal error. This is in version 3.5 of the plugin and using WordPress 3.3.1.
The error should be something similar to:
– Catchable fatal error: Object of class stdClass could not be converted to string in /home/blondish/public_html/wp-includes/formatting.php on line 805
If you are upgrading or have already upgraded your Yet Another Related Post Plugin, please check your website. If this fatal error occurs on yours, simply deactive, delete, and go to the YARPP download page in the WordPress plugin directory and download the previous full version of the plugin. The previous full version would be 3.4.3 and you can find it by going to the link that says “Other Versions.” Install that versiion, adjust the plugins settings, and you should be good to go.
