Warmane site SSL Certificate issue

Hi, I would like to bring to you attention that there is a certificate issue when browsing some areas of your website:

The account page does not show this issue, but some other pages do show it.

I am simply bringing this up because I haven't seen this issue before and maybe requires the Warmane staff to look into it.

Is it common to everyone? Or just for me? Should I be worried?

Regards


** EDIT **

It seems that manually navigating to the https protocol version of the page works. Example https://forum.warmane.com/

But the following site header buttons for "Forum" and "Armory" navigate to the http counterparts instead
