I’ve used ACF before, so I am bit surprised why this doesn’t work.
Basically, I’ve created a custom field called 'external_link' as slug and used the following code to display it on the page and it shows on the page whatever was inserted in the field.
<h2><?php the_field('external_link'); ?></h2>
However, when in the same group, i’ve created a second field, also a URL field, I called the slug 'abouttwo' and used the very same code: <h2><?php the_field('abouttwo'); ?></h2> and whatever information is placed there does not show up on my page. As I said, they are in the same group and have the same behaviour.
Does anyone know what causes this?
If everything is as you say then there is no reason it should not be working.
Except may some type of cache that is showing old data.
Double check your work?
