I use amember and the wordpress plugin with no problems, today I upgraded to the latest amember and my amember dashboard protected page body text is significantly smaller than it was before the upgrade. Usually it simply uses my wordpress font and size however that is not currently the case :/ Any insight? Does anyone know what the css class for amember body text is, I'll just modify the site.css
Did you clear your cache, after an update things can seem broken but it is only old stuff infesting the content cache of your browser. Check by using a different browser if you are able.
