Cant add products to WooCommerce

Hi,

Would love some help. Had a guy do my seos and now my website seems to be falling apart. I am a newbie so apologies for the simple language.

I cant seem to add any products or media. The page is layed out to enter a product but in the review section where you use the button to add the product the button has now changed to “submit for review” then this page goes to the posts page instead of adding the product.

I am also receiving this message just below the title: You are currently editing the page that shows your latest posts.

I had a suggestion from a friend to clean the cache which I have done but didnt fix.

Any help to fix this would be appreciated.
