Hi there,
It's important your screen shows the left navigation menu so you can use your account with ease. Rest assured, I'll help get everything back in order so you can get back to doing what you enjoy.
First, I'd like to start off by doing some troubleshooting to determine if this a browser related issue. When was the last time you cleared cache and cookies on your browser? Doing this will help fix most issues the site may be having. Here's an article which shows you how to do that: How to clear Cache and Cookies. Give this a try and let me know how you make out.
