The WordPress theme developed by nicetheme is based on the Advanced Custom Fields custom field plug-in. We have integrated the core module of ACF in the building block plug-in.
If you have secondary development needs, you can also develop based on ACF. Of course, if you cannot complete the development, you can also contact us, and we can provide reliable high-quality development solutions.
Then, if you want to enable ACF, you only need to install the building block plug-in instead of installing the ACF plug-in (installing the ACF plug-in at the same time will give an error message).
Then in the functions.php Or the nicetheme root directory functions_xxx.php (xxx is the subject name, such as cosy funcitons_cosy.php ）The ACF module can be activated by inserting the following code into the file.
add_action( 'init', 'show_field' ); function show_field() { add_filter( 'acf/settings/show_admin', '__return_true' ); }
