 * On php 7.1 I have such errors
 *     ```
       Warning: Illegal string offset 'uri' in /server_path/wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 861
   
       Warning: Illegal string offset 'blog_id' in /server_path/wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 862
   
       Warning: Illegal string offset 'post' in /server_path/wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 863
   
       Warning: Illegal string offset 'key' in /server_path/wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 864
   
       Warning: Illegal string offset 'headers' in /server_path/wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 870
   
       Fatal error: Uncaught Error: Cannot use string offset as an array in /server_path/wp-content/plugins/wp-super-cache/wp-cache-phase2.php:870
       ```
   
 * To resolve the problem we need replace variable type definition:
 * `$wp_cache_meta = '';` to `$wp_cache_meta = array();` in `wp-cache-phase2.php`
