After trying to replace wording i get this error message at the top of the backend of the page similar to this:
Warning: Illegal offset type in isset or empty in /wp-includes/post.php on line 828
It only shows on the find replace plugin page when the script is run.
This is a known bug, yet I do not now how to solve this. I’ve seen it sometimes on my own installs, but it does no harm.
From digging around on Google, I saw this response to a similar situation:
“Basically, you have a plugin registering a post type incorrectly, and then core complains.”
I don’t know if that helps or not.
unfortunately I do not register any (Custom) post type. This bug is on my todo list, but you can safely ignore it for now.
