 **Case**

 When switching a default theme (Twenty Nineteen) to a custom theme (made
 by me).

 **The Problem**

 The plugin `advanced-custom-fields-pro` isn't activated so it displays an
 error.

 I tried to fix it without touching a database by adding
 `activate_plugin()` function.

 {{{#!php
 <?php
 if (!function_exists('get_field') ) {
   activate_plugin('advanced-custom-fields-pro/acf.php');
 }
 }}}

 Following those documents:

 https://developer.wordpress.org/reference/functions/activate_plugin/
 https://developer.wordpress.org/reference/functions/get_option/

 **The error returns**

 {{{#!php

 Debug

 The debug returns get_field('activate_plugins') doesn't return an Array as
 it described there (https://codex.wordpress.org/Option_Reference). It
 returns string with `i` and `s` looks like a direct query from database
 row.

 So I wish to know how exactly to activate a plugin correctly?

 `get_field()` is not a WordPress core function. As noted above, please try
 the support forums.
