I have a website having pages like login.php, home.php, register.php. All the essential pages for website operation are in php, my website generates a url as - website.domain/username.html every time a user registers for his/her profile (for other operations).
I want to remove using this .html at end of the links and want to have link as- website.domain/username.
I am hosting my website on 000webhost and I am aware of .htaccess file but still I don't have enough knowledge to use htaccess, I tried htaccess method but it crashed the site.
