In your xampp\apache\conf\extra you have a httpd-vhosts.conf file
Add a new virtual host that points to where you have your webpanel installed
The ServerName directive sais that the webserver will show this page when it gets a request for the specified server name.
Ofc you have to make sure that the request gets to the webserver.
If you dont use a FQDN (as I do for my dev install) you could do this with a entry in the hosts file.
Dont forget to restart your apache after changing the file
PHP Code:
<VirtualHost *>
DocumentRoot "F:\XAMPP\htdocs\WebPanel-Core\public"
ServerName webpanel-core.local
<Directory "F:\XAMPP\htdocs\WebPanel-Core\public">
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
