Paragraph breaks have disappeared

There don’t seem to be any paragraph tags in that text on the home page. Did you change something? Have you tried deactivating your plugins and switching to the default theme to see if any are causing this?

Have you tried reinstalling the theme? (Note that any changes you’ve made to theme files will be lost.)

No. Your plugin settings are saved in your database and should be retained for future use.

I should contact the maker of this now

Yes.
