It is possible that something is MITMing you and changing your cookies. Have you tried a VPN or proxy so that your connection gets routed elsewhere?
Given that other people have no such problem, I am willing to bet that using a VPN or even just a different port number would solve it. But even if it is caused by my network having some routing/caching issue, that is not a permanent solution IMHO. psx-scene also gave me this same problem for quite a while, although the issue disappeared at some point.
I doubt it is really a MITM attack because:
- Who am I, to be a valuable target.
- What is the purpose of such a move, which causes nothing more than an inconvenience.
- Why am I only affected on this particular website.
- Why am I affected on both my mobile connection (which gives a different IP address) and my wired connection at home? However, I am using the same ISP for both mobile and the wired connections.
- Checking the "remember me" check box works around the issue.
EDIT: Please disregard what I wrote about cookies expiring.
I just found out that some cookies like _gat, are deployed for
Google Analytics. That cookie is meant to expire after a minute.
Xenforo is just returning code 301 and issues a new session cookie, whenever my session expires.
Here's what the site looks like with HTTPS:
Here's what the site looks like with HTTP:
Fair enough, but I still think that this is another thing that the admin(s) may want to look into. Here, there is some issue with state management, which I doubt is related to what you want.
It's due to xenforo saving formatting, which disregards the current color of the theme. I'm not sure if the "ctrl-shift-c" shortcut works which will allow you to paste without formatting. If that doesn't work, a workaround would be to paste the text as usual, highlight the offending text, then click the button with a T with an x to it on the right side of the toolbar.
The copy+paste bug only seems to affect this website. I've been on another website that uses Xenforo, and I don't remember anything like that happening.
I just tried CTRL+SHIFT+V and I could paste your quote here, with no issue. Thanks for the tip.
