Conflict with theme DIVI

Hello, I have noticed an error in the debug.log:
“PHP Warning: mysqli_num_fields() expects parameter 1 to be mysqli_result, bool given in ….wp-includes/wp-db.php on line 3547”
I found out, that it is this plugin, the error went away when I deactivated it. Is there anything I can do, to prevent the error and have the plugin activated?

Thanks
Christa
