I deleted everything below htdocs previously (as stated in my post Feb 20 6:23pm). The files that are there now were created/modified Feb 21 12:53 pm which was not done by me. I haven’t touched anything since Feb 20.
I’ve tried to login in to WP & not working. So again I’m deleting all files under htdocs.
Those folders don’t affect your website, but some of them do store some internal data from Softaculous.
Seeing how you don’t have any other sites on the domain, I think it’s safe to delete them and try again (you may need to login again to make it work).
You should just be able to leave all those settings default. Softaculous will then setup a new database for you to install WordPress. That’s the option almost everyone uses.
The point of having Softaculous integrated with the hosting platform is that stuff like setting up databases is done automatically. If you don’t mind that part, you could also go with Softaculous Remote or Installatron Remote to install WordPress. Or just do a manual install.
What do you mean? There is no limit on using FTP to upload files.
If you are using the online FileManager, it just simply can’t handle large uploads, but connecting to our servers by using a desktop FTP client like FileZilla will work just fine.
