Sorry, I couldn’t reply but this is what I would have said to your post
I had already moved a domain & because it was a free service, I wasn’t eligible to have website migration, which in itself is fine, but then out of the blue I started getting the orange screen saying the website was coming soon, when my site was working previously & I had potential clients viewing the site, now the only thing I see is that damned “Our website is coming soon” message
Your current website install is corrupted due to either issues from the client area or your excessive curiosity that pushed you to try the page builder option in the client area which destroyed your site.
In either cases, follow this guide. It’s for WordPress, but can also be applied to whatever software you are currently using.
Did you use the Site.Pro website builder by any chance? I don’t quite know how it works exactly, but it seems that this coming soon page is published by the Site.Pro builder.
Unfortunately, when Site.Pro publishes a website, they will indiscriminately overwrite any files already there. Including the index.php file from WordPress.
To restore your WordPress site, you will need to replace the current index.php file with the index.php file from WordPress, roughly using the guide that @Meishin pointed out.
