It could be something as simple as your home page now being index.php rather than index.html and the providers default index.html being displayed as that’s what browsers will default to if there are both html and php pages.
Or, you might be publishing to the wrong place on the server.
I’m assuming here your homepage is index.html or index.php?
The host guide doesn’t help much, as it doesn’t say where on the server you should upload to. Often you need to upload to the /public_html directory. When you go to the RW publishing window and click on the ‘Browse’ button, what do you see? A screenshot of that might help us to help you.
This is what I see when I use the RW publishing ‘Browse’ button. See how my website is published to /public_html and you can see the index.php in there which is my home page.
This is what I see when I click “browse” on the upload options. I did click on the index.html option and it started looking like it was publishing but it didn’t make any difference. It was maybe a rookie move on my part…
This tells you to upload files to the folder you see and warns you not to load any files outside this folder. You are effectively uploading your RW files to a folder called /www.supermarkmusic.com/ which is incorrect. So your web files on the live site would be in https://www.supermarkmusic.com/www.supermarkmusic.com/ if you get my drift?
I don’t know how up to date the lcn support page is, but the instructions on the page suggest that the correct path is in fact /www.supermarkmusic.com/web/
I think that’s the best option. Get them to look at your hosting space and see if they can see your uploaded files and if they are in the right place. It’s easy for them to just say it’s RW - and it still might be if you are uploading the the wrong directory - but get them to look.
I’d always advise using an FTP app to look at the hosting space too. You don’t need to use it to upload, but you can see much more of how the directory structure on the server is configured.
