    Hi @tigere

    Have you added a custom meta key value for any of the post meta values for that at_biz_dir post type?

    Can you try turning off all of the meta values from the settings page for at_biz_dir and see if that resolves the error. If it does, try and turning them back on one at a time, to check if it’s just one meta value or all of them.

    The ‘custom_key’ value should be set in the database when the settings page is saved, even if it’s an empty value it should still exist.

    I’ll do some testing to see if I can replicate this before you have a chance to test, but if you could test and provide some additional info. that would certainly help find the issue on my end (since we don’t have the same data on the settings page)

    Thanks,
    Evan

    Thanks for the assist the listings are now displaying by switching off the meta values

    I will try the meta values one by one and see if l gt any problems but switching them all off the listings does show
