I had problem with installing demo site. Demo importer didn’t work. I did it manually, but during installation and activation plugins, still some errors occurred, especially when I marked all plugin to proceed (WordPress 4.9.5). I had to install and activate plugin by plugin.
I had also problem with all-content.xml file. I had to import this file a few times. Finally I had to setup all settings (menu, megamenu, etc.) manually.
Some submenu item direct to your demo site (Blog->Author, Archive, Blog None sidebar, sidebar left, right, Portfolio-> Single column, three column). Menu-> New Posts (is inactive) It’s correct?
I have problem with: Best seller products, Related products, Up-salles and New products on the main page (and on the all pages where they products are showed). <b>Instead of price I have red stars,</b> and yellow on the right side, despite I turned ratings off.
I don’t use Twitter. It’s possible to put in that column another content like text, maps or widget?
