Hi,
I’m able to see the custom fields in the editor, but when I go to the page I can’t see anything I typed there (using text area fields).
Do I need to change something or? Using default WP theme (2014) with no plugins.
If you need to display the values in the front-end means
take a look http://www.advancedcustomfields.com/resources/displaying-custom-field-values-in-your-theme/
Or if you want create front-end submission means you should create a page first using acf_form_head() and acf_form()
take a look
