If you have cPanel access, you can just login to your cPanel and locate the file you want to edit. Or you can use a FTP client to connect to your web server, login using your ftp login details and just right click the file that you want to edit, apply all necessary changes and save the changes.

FTP, SSH ... although they're probably overkill for you. Anyway, do what Chris recommended you: Update the question with the details about your problem. What kind of site you want to access? How did you use to access it?

If you can't remember how to access your own website, then you have to let your website go, and start over.

I had the same problem as you, and I was not able to access my own website.

Next time you need to access your website, should take notes. Because it helps you to remember how to access your website if you want to edit something that's on your website.

Explain your question.

haven't accessed in a while and I don't remember how to access to edit the website.

Awesome. So what's your problem then?
