When adding in code using the code block, the text is much too small, can I change that?

Hello, I use wpforo and I have the following problem, when I’m in the forum, the widget buttons are visible, but when I go to the home page, for example, the buttons disappear, and your theme is great and I want to use it, I even thought of buying the pro version, but I still don’t dare with this problem

I am attaching pictures of the problem

I want to put an excerpt on the home page under the Headline, there is an option in the backend of the post but it does not show on home page? I have tried to edit function php with extra code but it won’t let me edit
