Need Help I am stuck

Hello I have been using this team for almost a year, and I simply LOVE it. But for several months I am stuck with issue of horizontal bar, my content is wider than screen. Not just on google, but all browser. And not just from mobile devices but desktop too. Increasing font size (which currently is 17) of all posts didn’t help, neither did resizing picture change anything. Please help out.
