XenForo - Reactions option not showing

I have got the Xenforo (2.1.4) installed but I am not able to see "Reactions" option under the "Content" section. I tried to disable all the addons, I tried to uninstall all the addons, I tried to update the theme but I get other SQL errors, unfortunately I can't see the "reaction" section in the admin panel. I think it's a SQL problem, maybe some addons I installed will have deleted some tables. Can anyone help me solve this problem? I inserted the image attachment to show you how I should see the reaction section, thanks in advance.
