I apologize for any inconvenience you may have experienced. Allow me to provide you with an explanation.
Upon the installation and activation of the WooCommerce plugin on your website, it automatically incorporates the e-commerce functionality, offering users the ability to browse and purchase products. Consequently, the “Shop” page becomes accessible by default.
As for the “Visit Site Homepage” option, this is a standard feature of WordPress. Clicking on this option will promptly redirect you to the homepage of your website. Similarly, selecting “Visit Shop” will direct you to the shop page of your website.
Furthermore, our theme includes shop demos that, when imported to your site, replicate the shop’s appearance and content, including product pages. You will find the demonstration content on these specific pages.
You can edit the demo content by simply editing the pages as per your need. For a detailed explanation about our theme and WooCommerce functionalities please check the below articles of WooCommerce and our PORTO Theme.
I trust this clarifies the functionality for you. If you have any additional questions or require further assistance, please do not hesitate to ask.
