Sorry for the newbie questions.
I have a single user free account.
For previous upgrades, I simply uploaded the new files, visited the site, an upgrader ran, and it was all set.
I uploaded the new files and now all I see is
MySite.com can’t currently handle this request.
HTTP ERROR 500
I am not a server person, could you offer simple instructions on how to fix this?
I am running php 7.4
