Fatal error: Uncaught exception 'InvalidArgumentException' with message 'Passed variable is not an array or object, using empty array instead' /wp-content/plugins/wordpress-23-related-posts-plugin/config.php:69
Stack trace: ... #8 /wp-content/plugins/wordpress-23-related-posts-plugin/config.php on line 69
We're getting a blank screen and found out it was caused by this plugin with the errors above. Tracking back we found out that it was caused by uploading a default image. We both tried it on live & local servers to upload default images and both caused that error.
We tried putting a condition for config.php line 69 to execute that line when it's an object or array but we noticed that doing so will not display the related posts on posts.
Then we've tried fixing the error by the solutions posted here http://zem.si/15iW3LC which solved the problem by deleting those entries from wp_options, but it's juz temporary. Coz everytime we use the uploading of default image it's back. So temporarily we commented out that section of the code.
Hopefully you could fix the part of uploading of default image which causes the error coz we love your plugin! Thanks :)
