Template not found: $PRIMARY_SITE_URL/$PRIMARY_SITE_URL/blog/this-is-my-blog Very new to craft CMS, recently just installed XAMPP with php 7 and craft 3 and followed the getting started tutorial from Craft CMS. Then when I try to preview or open the page created from the tutorial, it gives me a 404 template not found error.
The error is as follows:
yii\web\NotFoundHttpException: Template not found: $PRIMARY_SITE_URL/$PRIMARY_SITE_URL/blog/this-is-my-blog in C:\xampp\htdocs\craft\vendor\craftcms\cms\src\controllers\TemplatesController.php:92

and it looks like this:

I have followed all the instructions in the tutorial, and have created the _entry.twig in my templates/blog folder. Any help would be much appreciated
You have to go to your Admin Dashboard &gt; Settings &gt; Sites &gt; Your site and delete Base URL field, then save it and try to navigate.
