It's crazy that ALL links on my webpage turn to HTTPS now

My server OS is CentOS 7 64-bit, then I installed VestaCP to provide LAMP environment for my website.

There is only one website on this server and I applied free SSL Certificate for it and turned on SSL option on VestaCP panel.

Now, every link, all links, on my webpages are turned to HTTPS, including links to other 3rd party websites.

For example, my forum is built with Kunena component (one of Joomla extensions), there is a copyright link for Kunena official website below the forum pages. That link was inserted by Kunena software itself. That link is a non-SSL link before I enable SSL for my website. The link was:

Code: Select all

http://www.kunena.org/

And now after I enable SSL for my own domain ( www.joomlagate.com ), the link changed to:

Code: Select all

https://www.kunena.org/

I have no idea what kind of mechanism had turned this link to a SSL link?

This is just one example, in fact, all links on my webpages, including all those linking to external domains, are turned to SSL/HTTPS links!

Even when users post on my forum, they insert a link as "http://www.something.com", this is a non-SSL link, after the post submitted, it will be shown as HTTPS link on the forum page!

I think this is crazy!

Maybe it is because I had enabled HSTS header for a while? But I had already disabled that header.

This issue is not browser related. I had changed 3 different browsers, but this issue exists on all of them.

I think this is something related with VestaCP. So I post here to see maybe someone knowing VestaCP well can help to fix this.

Thank you.

Do you use some CMS? Maybe some plugin is doing this? VestaCP doesn't change your web pages.

Yes, I use Joomla CMS to build my website, but I did not use any plugin/extension to do SSL job.
