I can't share my posts in twitter or facebook

Hello, I have a wordpress site with infinityfree free hosting. I tried to install a plugin to auto publish my posts in facebook and twitter, but there is no communication with the site and the social networks. I would like to know how to fix this. I really need this for my growth plans.

any help will be very welcome.

Access to the APIs of social networks is blocked on free hosting due to abuse (spam bots and the like). You’ll have to upgrade your account to access such APIs.
