The screenshots quite clearly show a few issues:
- Your subdomain is linked to the directory
pokedexbysk.rf.gd/htdocs
, but you uploaded your files to thehtdocs
folder. Recreate the correct directory and move your website files to it: How to move a website to a different directory - The website files appear to be uploaded to a subdirectory. So if people try to access
pokedexbysk.rf.gd
directly, they will see the standard welcome page. If you want the files in that subdirectory to be your entire website, you will need to move them out of the subdirectory and place them directly in the htdocs folder of your site.
Note that both of these things are also explained the 404 error page article you were linked before. So either you didn’t understand the article or skipped past it entirely. If something about the article isn’t clear, please say so so we can try to improve it.
