How can I edit my name and description without all in seo plugin

Im trying to make my webpage look simple and clean but I notice that my name on google appears with a line in the side of my title when it shouldnt be there! and none of my descriptions for pages appear yet! So I erased all in one seo and I want to change it through code. My website name is andreyaniv.com and in chrome it appears as Andre Yaniv |
also many pages which dont exist anymore keep appearing high in search results what can I do about that? thank you

Hello Andre,

Your issue looks like general WordPress issue.

I kindly suggest you to use WordPress.org forums to find solution, that forums is the right place for general WordPress questions.

Kind Regards, Roman.

oh ok thank you
