In the meantime, several users have reported that Twitter has become obstinate. Valid pages and accounts suddenly don’t appear to exist, even after typing in a direct Twitter URL. Forget checking your mentions (the tab with the @ thing) or follower/following lists; they just hang.
It’s probably not your account at fault. Chances are, you can access things just fine through a management tool like Tweetdeck. In fact, power users might not even notice a problem in dealing with Twitter through its own interface, simply because they rarely use anything but management tools.
If any of this sounds familiar, try this simple solution: Clear your browser’s cache.
This solution is so basic and so often used, yet it has eluded experienced web surfers on this point. It’s completely understandable: The characteristics of the problem scream that it’s a server or account glitch, and it’s happening at the same time as a major rollout. Clearing the cache looks like it’s too simple a solution and applied in the wrong place.
But it seems to work.
“Great Googly Moogly, Kim! That’s wonderful! But how do I clear my cache?” Good question. In fact, it’s so good that wikiHow has a page for it: http://www.wikihow.com/Clear-Your-Browser’s-Cache . Not only do I not have to reinvent the wheel, I don’t have to guess at the flavour of browser you’re using. (If you’ve never used wikiHow, feel free to wander around that site for a while. It’s amazing what people will explain when they have a place to do so.)
