This might not be the correct forum/topic, but I did not find a better place to post this:
When I visit the website, my browser (Firefox) alerted me that there are security issues with the website.
When I looked into it, I noticed a few issues:
1. At the bottom of the website it loads an image from sourceforge.net and explicitly uses HTTP (instead of HTTPS). The link is: [http://sflogo.sourceforge.net/sflogo.php?group_id=152568&type=12] Changing the 'http' to 'https' should be sufficient to solve this issue. search keywords: Mixed content blocking in Firefox
2. When visiting http://sweethome3d.com , your website does not automatically forward me to the https://.. version of your site, which it should. This allow MITM hackers to have your website visitors download virus-infected copies of your software; additionally, it lowers the search engine ranking and the security warning might scare off visitors.
3. The current webserver software is outdated (Apache 2.4.38) and might be vulnerable to various security issues. You can check this using: $ wget -q -O- --save-headers sweethome3d.com | grep '^[Ss]erver:' | awk ' {print $2}' Apache/2.4.38
