Error is adding directive to .htaccess file.
Open prestashop / modules / watermark / watermark.php
In line 298, remove Options + FollowSymLinks.
File Save
Go to SEO settings and disable friendly URLs.
On FTP, delete the .htaccess file.
Turn on SEO friendly URLs.
It should work.
Many thx. Will try and see how it comes out.
