I was getting the following error message:
Warning: array_merge() [function.array-merge]: Argument #1 is not an array in /home/alrba/public_html/wp-includes/post.php on line 2996
So I turned off all my plugins and it went away. I started turning on my plugins one by one and only when I turned Event Espresso on did the error message pop up again. Seeing this, I deleted the version, downloaded and reinstalled the same (most recent) version. I am still getting the error message. This is apparently causing one of my registrations not to work as I have received a complaint from the client.
This has been reported once before, and it was resolved by setting the cancellation page setting in Event Espresso>General settings to a page that exists. Can you check your page settings and verify that they are set to pages that are published?
