From Italy, same problems as described above, sometimes when loading for the first time, sometimes when signing in. To me it started happening a few months ago, when the initial dialogue box about privacy to which you have to agree was put up.
As I cancel all cookies every time I close down the browser, I get to agree to it at every new browser start, but that's my problem.
The funny thing about the dialogue box is that it loads after the home page is loaded. If I click a link and open a thread in a second panel before the dialogue box appears, I get to agree twice, once in the panel with the home page and once in the panel with the thread I just opened.
I think this order is strange. First you agree, then the home page loads and the links on the home page become active.
