Hola. Cuando ejecuto el kickstart.php me da un error cuando se crean las tablas de la base de datos:

Database error processing line 36
Database server error reply:

ErrNo #1071
Specified key was too long; max key length is 767 bytes
SQL=CREATE TABLE `qsv3t_akeeba_common` ( `key` varchar(192) COLLATE utf8mb4_unicode_ci NOT NULL, `value` longtext COLLATE utf8mb4_unicode_ci NOT NULL, PRIMARY KEY (`key`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci
Raw query text:

CREATE TABLE `#__akeeba_common` ( `key` varchar(192) COLLATE utf8mb4_unicode_ci NOT NULL, `value` longtext COLLATE utf8mb4_unicode_ci NOT NULL, PRIMARY KEY (`key`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

Que podría estar pasando?
Gracias
