I have a True/False field on an ACF options page which I’m using in conditions, in addition, I have a custom function that also returns True/False that I use in conditions. I check against these using either == 1 (for true) or is_blank (for false). This is all working just fine and how I would expect on the website itself.
However, I’m getting this in the debug log in regards to both of those conditions. PHP Notice: Undefined offset: 0 in wp-includes/class-wp-query.php on line 3300
Any ideas why this could be occuring and how I can remedy it?
