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.
EDIT
Simply ZIP all files from cPanel and download the ZIP. The problem will be solved.
Hope this is useful
RE-EDIT
In FileZilla => Transfer > Transfer Type
I had "ASCII" selected: by setting "Binary" the problem is solved.
