Easy social showing code instead of text

I just updated to Easy Social 1.2.3 and am using Joomla 3.31, and now there's code everywhere instead of buttons or links. For instance, in the profile area of the frontend, instead of a button to select female it shows "PLG_FIELDS_GENDER_SELECT_FEMALE" This is throughout the site (in the front and backend). I've purged the cache, and tried other things, but didn't solve it. Is this a problem with a language file? I'm not sure.
Also, I want to migrate Community Builder, but when I click on the migrate button, it just stays at 2%. CB is up-to-date. I don't know if the two problems are connected.
Thanks for any help
