This is getting really really annoying:

whenever I click a link on this site (no matter if store or forums), I get redirected to a "oops 404 please login"-site.
The only way to see the desired page seems to be clicking the back-button of my browser (firefox and likewise chrome) until the page actually loads.

I don't know if this is some cookie or session related problem, but please do fix this!

edit: ironically, the exact problem happened after I posted this post
I got redirected to https:*slash**slash*secure.gog.com/login which then shows an "oops"

after clicking back 3 times, I got back to the actual post

Try clear cookies completely and relogin

In Firefox:
CTRL + SHIFT + SUPR

Or the ultimate clean technique:

Delete the profile directory of Firefox. in linux is:

$ rm -r $HOME/.mozilla/

I'd bet many English-speakers might not know the Spanish "Supr", but might more readily recognise "Del". Then again, the same key in German is "Entf".

Or anything-else-besides-whatever-language-that-is-from-speakers, for that matter. When communicating in English, always use the English names as well.

This is also why I prefer having both my OS and applications in English. If I need to look up a problem or something online, it's much easier if I know the English name of the related option/function/button/menu/whatever.

Then again, we are perhaps blessed (or not, depending on viewpoint) in that our languages are so small no one generally bothers to translate for us, so we have the English labels on our "named" keys.

I do agree with you, though.

Spanish, French and German are so large that they likely seldom need to search for English-language solutions to their problems.
