After some time I downloaded a copy of a website via FTP. I made a comparison with SVN and I find out that each file was modified in this way:
BEFORE
<div class="class">
<p>TEXT</p>
</div>
AFTER
<div class="class">
<p>TEXT</p>
</div>
Is there some option that could cause this behaviour??
Thank you
I found out where the problem is.
I didn't upload the files via FTP. I used cPanel.
cPanel 66.0 (build 17)
EDIT
To by pass this problem
Simply ZIP all files from cPanel and download the ZIP. The problem will be solved.
Hope this is useful
RE-EDIT
To solve the problem
In FileZilla => Transfer > Transfer Type
I had "ASCII" selected: by setting "Binary" the problem is solved.
