Comment accéder à un site pour le modifier

The best thing is to ask your host. Normally, there should be icons to click to delete, modify... the file.
Okay, goodbye.

Hello,

You need to download the files you want to modify, edit the files locally (once they are on your computer), then save the changes and upload them back to the server once the modifications are done. Make sure you don't mix up the directory when re-uploading the modified files, otherwise nothing will happen when displaying the site.

So I see two possibilities:

- Either there was an admin area on the site. In that case, you need to know the address of that area. Apparently you have access to all the files of your site, so if you see a folder called "admin" or something like that, then that must be it.

- Or you manage your site yourself by modifying the files and uploading them to your site's server via FTP. Apparently, you have access to FTP: what software are you using?

ftp: Your file list is the files that make up your site. With FTP, you can modify these files and therefore your site. To do this, you actually need to have two file lists: the first is the list of files on the server hosting your site, and the second is a sort of explorer, which is actually your hard drive, your local files. The idea is to choose a file from your second list to upload it, meaning to place it in the first list.

File hierarchy: when you open your FTP access to your server, you normally arrive at the "root" of your site, meaning you cannot go higher in the folder hierarchy. At this point (the root), you should find a file called index (.html or .php or .htm, at least something with a point). This index is the first page of your site. So you should start there if you want to understand how your site works.

I'll stop here, not too much information at once.

To help us understand your situation better, what do you know about the subject: languages (html, php, css ...), SEO... How much of a novice are you?

Give us the address of the site, if it's online of course. That will help us.

Good luck to you.
