How to fix some white pages of death on Kloxo control panel

I’ve just debugged a site and I could not find any clear problem and none of the known solutions worked.

The site is running on a server managed with Kloxo (Open Source version of cPanel/Plesk).

What happened? I had the white page of death everywhere, the website was completely broken.

Why?
I knew that Kloxo is adding some lines to the .htaccess file, but until now it did not break the sites. This time it did. I guess it has something to do with the server specific configurations.

The solution was to delete those lines of code and leave only the original .htaccess insertions wordpress wrote there.
