Is your account currently set for admin? It might have been changed by your coder. Also is this a multisite WP install? If so your coder might have “super-admin” rights.

You could try Customizr theme, I have several sites with totally different layouts including portfolios. Their support is awesome and it’s free. They do have a commercial version also.

Suggest going to woocommerce’s support.

The best way to make changes like this to a theme is to use a child theme, so your tweaks won’t be overwritten when updating the theme. Here are some guides in case you haven’t made one before:

You should also check this out for customizing your site.

Then to edit this editor is fantastic. You can edit multiple files at the same time. This is a windows program.

If your using Customizr, then click on the help button on the top right of your dashboard, it will take you to the customizr support forum and other customizr stuff like code snippets. Those guys there know their theme better than anyone and are great help. Give it a try.

This should work for you. Add to your style.css

#respond .form-allowed-tags {
display: none;
}

Try this

#postid-3454 #header .menu {
    display: none;
}

Try this in your css, I know the first 2 selectors are correct, the post part I am not certain, someone correct it if I am doing it wrong. It’s been awhile since I added css to a single page/post.

#header .menu postid-3454 {
    display: none;
}
