Problem with links once in portfolio item

You should check your Appearance > Menus Select activated Menu & check its links by clicking on the name tab, you are probably using #Home link instead of using a full url of that specific page.

Example:

Home Url should be: https://epix.com.mx

You might be using: #Home

Update: If your website has more than one page/s than you should create separate navigation menus.

Separate menu for homepage & Separate menu for other page/s this way you can avoid css style conflicts. You should have an option to use separate menu for specific Page. You can use #home navigation as your homepage menu & other full link navigation for the rest of the pages.
