I’m having a similar issue in that I have used the given codes to remove the shopping cart and log in from all pages (thanks for your help), but it is still present on individual blog posts, i.e. not on the ‘blog’ page but when I click on a specific post to read it the shopping cart and login is displayed at the top again.
