For what it is worth, I have experienced the same thing a couple of times when traveling and accessing the site via mobile phone. I am not sure whether I used WLAN each time, but I did the last time which was last week. For me, the problem however went away either by accessing the match page again or by logging out and relaunching the browser.
Edit. I should add that the top-most player selection list (who is dressed for the game) was in these cases empty on both sides. Regardless there were 2-5 guys from the standard lineup I could choose for the game. Obviously something I could not replicate and was just happy to see it back to normal with little trouble.
