 * Hi
 * It is not possible to install Music Press Pro when ACF is already installed and
   vice-versa.
    That error occurs: Fatal error: Class ‘ACF_Taxonomy_Field_Walker’
   not found in ….\wp-content\plugins\music-press-pro\includes\admin\music-press-
   admin.php on line 257
 * Can you help me fix that?
