Warning: urlencode() expects parameter 1 to be string, array given in /wordpress/wp-includes/formatting.php on line 3909
I am seeing that in my error logs using ACF PRO when ever I update a post. I have the latest version of ACF PRO and WP. I also have the free version of ACF Turned off.
Has anyone else seen this error?
Also, I do not see this error when I use the free version and uninstall the PRO version.
As far as I can find, ACF never uses the function urlencode. Have you tried deactivating other plugins to see if that clears it up?
