See Screenshot of the field form I added with ACF for the field _catcbll_btn_label. It’s a plugin-specific field, but I added it as a custom field entry in the ACF plugin, so that I would have an form field to enter data in the product screen.
In the product post screen, I need to save this value a:1:{i:0;s:22:"Request Shipping Quote";} in the custom field _catcbll_btn_label to cause a plugin known as Custom Add to Cart Button Label and Link to display a shipping quote button. Yet the ACF or WP is not handling it correctly, as the _catcbll_btn_label field shows [""] when I refresh the product page after submitting the value a:1:{i:0;s:22:"Request Shipping Quote";}. Can you suggest anything helpful?
