Hustle installation issues

Hi,
installing Hustle was a huge problem for me as it didn’t create the necessary SQL tables initially and was error-ing on AJAX calls all the time. I had to run debug logging for that to become visible.

I tracked the problem to:

self::TABLE_OPT_IN_META => array(
“meta_id bigint(20) unsigned NOT NULL AUTO_INCREMENT”,
“optin_id bigint(20) unsigned NOT NULL DEFAULT ‘0’”,
“meta_key varchar(191) COLLATE utf8mb4_unicode_ci DEFAULT NULL”,
“meta_value longtext COLLATE utf8mb4_unicode_ci”,
“PRIMARY KEY (meta_id)”,
“KEY optin_id (optin_id)”,
“KEY meta_key (meta_key(191))”
)

in opt-in-db.php whereas my mysql server was spitting me unsupported collation.
I have no idea how often that happens and my hosting’s mysql might be a bit older, but once i changed the collation to “utf8_unicode_ci” it created the tables successfully and worked as expected from there on.

The thing is it never gave indication when installing that it couldn’t complete it’s full install preparation.
