When I am logged in to FTP server of a hosting, I can't edit files with gedit there. But I can do it with mcedit. How come? It would be much more convenient to use gedit without downloading each file everytime. But if FTP doesn't allow it, why is mcedit capable of editing on FTP side?

if you are speaking about the editor of midnight commander I think it downloads the file before editing and uploads back at the end.
gedit has a similar plugin.

how do you access your root user .. with or justif you use just su then try su -
sometime problem with gedit exists because you dont get the root environment

First run following command in terminal
$ sudo gksu nautilus

now open ftp account in directory. Type host address in 'Location' like this
ftp://name-of-my-host.com

it asks "connect anonymously" or "connect as a user", Select second option and enter username and password of the account.
Now open project directory and open files in gedit.

I don't think it will prevent you to save the files.

Take a look at screenshot.

I did not mention that I have MATE version of gedit, “pluma”. So I put those two files into /home/alex/.mateconf/apps/pluma/plugins and there's no plugin in settings. I expected this not to work from the beginning.

What I do to edit files with mcedit is I `cd` into FTP dir, select a file and hit F4. It opens in mcedit and is ready to be edited. I don't think mcedit actually downloads files...

I do it this way: open ftp dir in mc, navigate to a file and type in command line of mc “pluma [ALT+Enter]”. Then I get error “Cannot execute commands on non-local filesystems.” So adding sudo will not make any difference there; I tried.

I don't have Gnome/Mate environment, just pluma. I operate with Midnight Commander.

P. S. It's not that important to be able to edit files on FTP with pluma, I just asked to know why pluma is not capable of doing thing that mcedit is capable of.

so please open a file (with mcedit from a remote ftp site) and execute the following:
ps -ef | grep mc
you will see the following result (or something similar):
....... mc
....... /bin/sh /usr/bin/sensible-editor /tmp/mc-<user>/ftpfs<some file name>
....... /usr/bin/mcedit /tmp/mc-<user>/ftpfs<some file name>
....... grep mc
From this list you can clearly see mcedit opened a local file in the /tmp/mc-<username> directory. The name of the file is ftpfs<something><original name>

So mcedit does not edit the file on the remote side, just the upload/download process is hidden.
using midnight commander and configure pluma as editor (in ~/.selected_editor) may work and F4 will open pluma for you. But I'm not really sure because I have no MATE.
