I'm making a theme to sell on theme forrest for the first time. I've used ACF as a standard plugin during development to make sure everything's working.
I've almost finished so decided to export my ACF to PHP and include it into my functions.php file.
I copy/pasted the code it gave me into functions.php and included ACF, options-page, and repeater-field into a folder within my theme and referenced them accordingly.
However, when I visit my site I get this error:
Fatal error: Cannot redeclare class Acf in /Applications/MAMP/htdocs/omg/wp-content/themes/omg-v1/external/acf/acf.php on line 46
I've removed the actual plugin files from the plugins folder also.
Any ideas why it might be bugging out?
I know it's a lot of code, but incase anyone wants to look this is the code that's in my functions.php (which ACF gave me)
include_once('external/acf/acf.php' );
define( 'ACF_LITE' , true );
// Add-ons
include_once('external/acf-repeater/acf-repeater.php');
include_once('external/acf-options-page/acf-options-page.php');
