Hi @caseysabella,
What type of issues were highlighted on your site that this plugin should help resolve? Equipped with this information, we would gladly guide you through the next steps.
In any case, the plugin will display the recommended actions to take in the Dashboard (located under “Security” in the left-hand WordPress Menu); though it won’t take any actions yet prior to you explicitly activating a feature in the plugin.
Feel free to open a new thread on the Support Forums for this plugin (https://wordpress.org/support/plugin/really-simple-ssl/), if you would like us to assist.
Kind regards, Jarno
