I know this doesn't have a effect on SEO and my page http://ps4on.com doesn't show any errors the human eye can see visually.

However, is there a way to fix these HTML validation errors? Is anyone else having the same ones I'm having?

I ran website auditor and it says "site has 802 errors and 212 warnings". 97 pages have errors or warnings. Only 1 page is valid.

There are 1805 errors and 5556 warnings for CSS Validation.

The theme looks nice, but that sounds terrible those numbers. Is there something I can do to fix all of those? And should I fix them?

That's way too many. With MZ done correctly, you should get 0. Only plugins give some.

You probably don't really have that many, though. If you find the right one and fix it, your numbers might drop to just a few, or even none.

There's a direct input option on both the w3c html and css validators. Instead of checking the whole page, if you do it in meaningful chunks, it might be easier to isolate your key errors that are throwing everything else off.

1) have you tried sutting off ALL plugins to see what effect it has
2) have you modified any of the theme virtual templates or CSS?
3) why do you care if it runs and it looks fine. Run the validator with apple.com or microsoft.com or google.com and look at the errors on them

That 1 page might be a good place to look. What's different about it from the others?
