Modify table to MyISAM, Try create full indexes and fail

Centos 7, MariaDB 10.2.11

Steps:

• mysql > use mydatabase;
• mariadb [mysqdatase]>ALTER TABLE dme3_posts ENGINE = MyISAM;
  Query OK, 22265 rows affected (40.65 sec)
  Registros: 22265 Duplicados: 0 Peligros: 0
• Click on button Create full indexes
  Fail:
  Fulltext Index creation did not work!

Check table on SequelPro (Result below. You see new fulltext key for title and content)

CREATE TABLE dme3_posts (
