How do I reset the options to see all news. For example a GOG posting briefly showed up in news; now ti is gone. I'm unsure if I have something that only shows certain news or if it was deleted.
So I think your settings may be the thing causing the trouble.
Did you accidentally select a filter? See the 3 lines behind "All news" at the front page.
Fixed it. What happened was that when you tick one of the boxes in the lower half, the news is filtered and it checks if the game the news is about matches at least one of the ticked boxes.
The issue was that in our database GOG is not a game, but an organization and it has none of the tags to compare with, so it would always always fail that check.
