Problems after upgrading Wrap7 framework

Hello,
I've recently purchased B2B Theme. After Joomla 3.7.4 brand new installation (without sample data), I decided to update Wrap7 framework to latest version following istructions here: www.joomlaplates.com/support/documentati...e-the-warp-framework
First of all make a backup of all the customized theme files, so you can recover it and redo all changes at any time.
Download the latest Warp version and extract the package to your desktop.
Unzip the downloaded files
Connect via FTP to your Joomla system
Copy all files and directories to /Joomla/templates/TEMPLATENAME/ and replace all files.
Joomla Admin > Template Options > Settings > Compile LESS
Delete your Browser and Joomla Cache
I did all this steps except the backup because is a brand new installation with only test contents.
As result I have a plain html page without any .css customization (as you can see in the attacced screenshot).
What miastake did I do? And how can I solve to have a working B2B theme and last Wrap7 version?
Thank you very much.

Hi there,
live url please!

Hi. Thanks for your kind attention.
The site i'm working on is www.cidipn.it .
I think now I've solved the problem reinstalling and updating framework again.
The first time I looked at this page: www.joomlaplates.com/support/documentati...e-the-warp-framework overriding whole B2B template's folder.
The second time, instead, I looked at this page: demo.joomlaplates.com/jp_b2b/docs/ where (at the bottom) you suggest to Copy all files to /templates/TEMPLATENAME/WARP and replace all files. (While in the previous page I mentioned at step 5 I find "Copy all files and directories to /Joomla/templates/TEMPLATENAME/ and replace all files.".
This different indications leads me to make confusion.
Now my question is: should I override all B2B's folder, or ONLY the WARP folder (as I did)?
Is there a place where I can give a look to be sure I did the update's procedure correctly?
Thanks in advance.

Hi there,
please unzip the update package and compare the folders with your folders on your server.
After that you know what I mean:

Hallo,
following the istruction and doing exactly as in the picture situation come back to the beginning situation as you can see at: www.cidipn.it/
I experience the same problem with Firefox and Chrome.
Where's my mistake?

Enrico

Ahhh I found your mistake.
You have delete the files before you update the WARP.
It is not needed to delete anything before, just override!

But for now you have to install the theme again and update the the WARP without deleting anything before.
