I'm getting this error:
Warning: array_key_exists(): The first argument should be either a string or an integer in /home1/mgould/public_html/healershearts.com/wp-includes/cache.php on line 725
and it's reading a pending release of February 3rd because of the cache issue, when the date is the 9th. I changed it to open today to see if it will stop the course from working, and it doesn't, so I know it's not the plugin. I just can't find anything anywhere to help me make it go away. I turned on debugging and it didn't help.
