To be fair to Gog, they've just fixed something that predated the downgrade: clicking on your username on the topbar used to bring up a 404 page if your privacy settings were cranked up. Now it shows your game library. Hurrah?

The Username still isn't even showing on the topbar, in IE11. But it did before the revamp.

Mea culpa.

Weird... It didn't work yesterday, it worked three hours ago, and now it's on or off on its own volition. This thing belies all expectations...

Could be an CDN issue.
GOG have a similar issue 2 weeks ago.
Everytime they claimed that they have fixed it, turned out that they did not. (Until their final fix, of course.)

Not one bit.

I like how right now on the front page, first thing I see on the list under now on sale is a completely broken icon.

I'm sure all the broken graphics, crippled speeds and generally confusing, shithouse layout are doing a wonderful job at attracting new people and not at all making GOG look like an unreliable site run by incompetents.

Edit: I just noticed a huge advert for thronebreaker when claiming the Jill of the Jungle pack... REALLY GOG?

I don't want your stupid card game, stop shoving it in my fucking face.

This was silently fixed few weeks (2month max?) after the privacy f*ckup, so this one is not result of redesign.

Although you have good point, the change did make it into redesign, which means that either:
1) they coded whole redesign in few weeks, starting from patched sources (would explain some of the quality, but not sure why GOG would rush so much, it's not like the old site was failing)
2) they have somebody on the team capable to merge patches into different branch ... that would sort of impress me, sometimes it felt like they have people who don't even use versioning tools.
3) they have somebody on the team capable to do that manually without versioning tools (i.e. somebody aware of what they are doing and why and how things work, although he's forced to suffer to do it in ineffective way) ... naah, can't be.
4) it popped out when QA was testing known test-scenario (created after that privacy backlash) and it got fixed ahead of release... Hm, but they don't have QA testing new versions of website, right, nor do they some kind of process of it? Can't be.

Sooo... which one is most likely? This is quite puzzling me, whichever you pick, it shows there's at least one person in their dev team somewhat competent... that's definitely new for me.

...
I must say, I really like the new website. The inability to find new releases if I don't check in daily and the Swedish prices (nearly tripled in comparison to my native Russian ones, yay shitty geolocation) really help me to get my game spending under control.

Since yesterday I can login now but still glitchy. Copy paste or bookmark a lower bandwidth intensive page like a random error page: https://www.gog.com/oaebqwkn , click sign in tab, click the purple sign in button, tap the down or up arrow keys a few times. The login frame appears 2-5 seconds later.
It will only appear once so if you exited the login frame, reload the page (F5) and try again.

If it gets too hard to login again I will have to dedicate an always signed in browser profile with a script to be sure there isn't another instance of the same browser running at the same time. Not looking forward for that. :/

All the problems in this thread have a mighty easy & ideal solution: rollback the site to the state it was in before the 10th anniversary downgrade/ruination.

Why hasn't GOG done that yet?

If I were a shareholder with influence, then I'd be demanding for that to happen immediately.

If GOG doesn't rollback, then most likely their income is going to be dropping significantly.

I second this. Dont know why it hasnt already happened, maybe we should start a petition or something...

Or they just didn't yet get around to making a new version of the sale page, since we had old-format sale pages after the redesign too, this recent trick or treat one being the very messy exception.

Did we? I must have missed that. I remember trying to browse both the anniversary and trick & treat sales and giving up fairly quickly due to the absence of a decent sale page. I can't remember what other sales we had in the meantime. Hmmm

Well hopefully this sale goes well enough to get someone at Gog who decides this stuff to realize what we've been trying to tell them.

This was since the change with these kind of weekly sales. It's probably not that they have rollbacked, but not yet reworked this.
