This has been an ongoing issue for years, at least on my system.
I use Google Chrome.
For me it worked without a problem (on Firefox), up until the forum upgrade/re-haul.
Сan you make the “thanks” button change color after clicking?
Just send an E-mail it doesn’t worky anymore to login and register a new account. But it seems it’s actual a metter from where i login? From the upper right i can’t login at all. Also to register a new account is not possible.
Anyway i’m here again and made it. 
Thank you!
That would be because I needed to change the cookies that the forum uses to remember logins, therefore basically logging everyone out.
Maybe, looking in to it
What would be your advice then, to stay logged in on the Gaki forum?
The automatic login is currently working on my system.
I don’t know if it’s Chrome that started playing nice or if you have made some tweaks to the forum behind the scenes.
Anyway, it works now.

Yep, it works on my end too (Firefox).
