For the past two weeks when navigating to my website, it displays a website with " Let’s Make Something Awesome" on it. I read other related topics but my website has been up since April and I can confirm that it was displaying correctly between April and August. When I checked the WP installation in Softaculous there was no trace of the installed website, it’s all gone! Which explains the default landing page. THree questions.
By wild guess, you might have installed the WordPress outside of the htdocs folder on your website. If you see htdocs right next to WordPress folders like wp-admin, then this is the case.
Just move everything back into the htdocs and you should be all set.
