it seems to me that it is something related to “utf8mb4_general_ci”. On old installations, even if upgraded to 4.2.2 tables are “utf8_general_ci” and they just work.

[Fri May 08 08:20:16 2015] [error] [client xxxxxxxxxxx] WordPress errore sul database COLLATION 'utf8_general_ci' is not valid for CHARACTER SET 'utf8mb4' per la query CREATE TABLE wp_2_terms (\n term_id bigint(20) unsigned NOT NULL auto_increment,\n name varchar(200) NOT NULL default '',\n slug varchar(200) NOT NULL default '',\n term_group bigint(10) NOT NULL default 0,\n PRIMARY KEY (term_id),\n KEY slug (slug(191)),\n KEY name (name(191))\n) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8_general_ci fatta da wpmu_create_blog, install_blog, make_db_current_silent, dbDelta, referer: https://xxxxxxx/wp-admin/network/site-new.php

this is the first error in my error log.

I’m not in hostgator

Same problem Here. Fresh installation, no plugin, default theme

Please note that the older installations, even id updated to 4.2.2, on the very same webserver work fine.
