Database Error on Clean Install?

[Picture-It-Sicily]

I'm receiving this error on the very last step of the install. The database is brand new, as well as a fresh install of PrestaShop on a subdomain for testing purposes only.

1: An exception occurred while executing 'SELECT t0.id_tab AS id_tab_1, t0.id_parent AS id_parent_2, t0.position AS position_3, t0.module AS module_4, t0.class_name AS class_name_5, t0.route_name AS route_name_6, t0.active AS active_7, t0.enabled AS enabled_8, t0.hide_host_mode AS hide_host_mode_9, t0.icon AS icon_10, t0.wording AS wording_11, t0.wording_domain AS wording_domain_12 FROM ps_tab t0 WHERE t0.class_name = ? LIMIT 1' with params ["AdminGamification"]: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away

 

I've been having some issues with my main shop after an update and rollback to 1.7.6, so I was just running through a clean test before completely starting over on the main site. I honestly have NO idea what this means though. I can figure things out but I'm not savvy with databases, or website building. I've looked through the database and Googled but everything that came up for a "fix" didn't work. I even recreated a new database and started over and still received the same error. TIA!
