How did I mess up this website?

So yesterday, I was browsing this website and I clicked on a a link like all of us normally do - can't recall if it was a giveaway or forum thread or profile, etc. But shouldn't matter what the link was I don't think.
Anyways, when the link loaded, I was logged out all of a sudden, which was odd since I'm always logged in all the time. No problem I thought and logged myself back in. No issues logging back in but one thing I noticed now is when I'm looking at the list of giveaways, the ones I've entered are no longer faded out. I always liked that feature cuz it easily displayed the difference between ones I've entered and ones I haven't. Now, since none of them are faded, when I look down the list of open or closed giveaways, all of them just look like they haven't been entered.
Edit: Oh, the other thing that this has caused is someone replies to a post in a thread such that the new post is indented, the entire post is blank and I can only read it if "reply" myself. Otherwise, it just displays as a blank post. Odd.

What did I do and how do I get that feature back since I thought it was a default feature? This is NOT SG+ as I've not used that yet. Thanks and hope this made sense to those who know what I'm talking about.
