I’m having the same problem with this plugin – my error message reads: “Fatal error: Call to a member function have_posts() on a non-object in /home3/bumpkina/public_html/wp-includes/query.php on line 641”
I contacted my web host for support and they said the error is with the plugin. That would mean a tweak would have to happen in one of the php files of the plugin that shows up on wordpress, right?
I’m very script illiterate and have no idea how to fix this without some serious hand-holding.
Here’s a link to the page in question: https://www.bumpkinandme.com/?page_id=1128
