Can't upload to root directory

[LordLiverpool]

Hello World

This is my first post, I am a noob, so please go easy on me!

Here is a little background info:

I got myself a VPS from 123-Reg in the UK.
I built a few websites and everything was going swimmingly well.
But then I wanted to do an e-commerce website with a shopping cart (oscommerce)
and a merchant account (Barclays UK Bank: ePDQ)

So I got this nice little connecting piece of php (oscommerce_epdq_payment_module_1.11) to link my site to the bank.
and the instructions say the code has got to be put in the root directory of the website.

So I go Websites & Domains > File Manager > Add New File > Choose File (callback.php) > OK
then I get the following error message:

Error: Unable to upload callback.php to /: filemng: Error occurred during /bin/cp command.

(See attached .PNG)

Now years ago I would've opened a unix shell and done su root and chmod 700
But because I now have Parallels Plesk v10.4.4 sitting on top on CentOS v6 r3.6.32-71
I am stumped???

Questions:

1.) Am I right in thinking that its a permission issue on the root directory?
2.) If so how do I alter permission on the root directory?
3.) Is the /: directory the root directory? I can't navigate to it in file manager
4.) Am I barking up the wrong tree? If so please help me!

I logged in with root and the password 123-Reg originally gave me but I didn't seem to have any "super powers".

I have wasted hours and hours googling for an answer. Please help.

Thanks in advance for your verbose reply!

Michael

The root of the website is actually /httpdocs which is where all your normal website files will be and that's the location they mean.

Note that if your oscommerce site is in a subdirectory, e.g. /httpdocs/oscommerce/ then it is possible they mean put it in there.
