My Mark all as read button was missing on the laptop in google reader this morning, and some other things didn’t look quite right (the google reader logo at the top left was missing for example). I tried messing around with greasemonkey and disabling the better greader extension and narrowed it down to something within greader. I then checked the skins option and noticed that it was setup to use the optimized theme. I switched the skin to none, pressed F5 to refresh and all my buttons reappeared and the other sections of the screen didn’t disappear either. Now I can mark my folders as read again and get my count back down to a reasonable number.
Finally, thanks! That’s been bugging me for weeks! 🙂
