QUESTION Not able to configure full toolbar ckeditor

[hameau]

It would be better to find out why you don't have gsconfig.php. It does much more than set the editor toolbar. Editing core files is not a good idea.

As you have only just started with a fresh installation, I would recommend deleting everything and starting again. If you are transferring GS to the web server using FTP, make sure that all the files are transferred before starting the installation. Also, I recommend installing the current version (currently v3.3.13) in place of the old version that you have.
