I switched to HTTPS for a few months but it was way more headache than it was worth. All it takes is someone to have an HTTP image in their signature and your trusted logo turns into mixed content some trusted and some untrusted. My site was also inexplicably slower while it was on HTTPS. I switched back and my site is noticeably faster again. I don't know how to explain it, but it was just a pain.

<a href="https://www.vbulletin.com/forum/articles/4361080-converting-your-forum-to-https" target="_blank">THIS</a> guide explains in detail how to convert your site to https. It's important to follow every single step.

For user-generated content where you don't have full control on the users' usage of http/https such as in signatures and post attachments, you can add this meta tag in the head to block mixed content. This way, your site will still show the green padlock icon in the address bar.

If you are on vBCloud, you can add it in the Google Ownership Verification HTML tag in AdminCP, otherwise, you can add it in the head_include template in AdminCP.

if that you could not successfully install SSL on your hosting and your forum is not complete running with SSL, you need to check if SSL is enabled on your hosting or not.

SSL are actived on my hosting, the fact is that the hoster says It's a vbulletin issue, and Vbulletin support says It's an hosting issue. Https works on the all site but the login box doesn't work...

What do you mean by "doesn't work?"

Is it redirecting you? Is it causing a white page? Is it giving an invalid login message?

It sounds to me like your .htaccess files are conflicting.

Delete all of them and reinstall only the one included with vBulletin.

on the first post of this discussion you can find attached the error I get, thank you
