Alright, then. If this keeps on happening, then it is probably time to clean out your cache information. A full cache usually leads to a few mishaps such as sessions timing out every so often. Here's how to clean it out, depending on which browser you use.
Internet Explorer
If using this browser, go to the top left corner of your screen. You should see a toolbar just below the search engine. Click "Tools", then "Internet Options".
A lit'le window should pop up. Currently staying on the "General" tab, search for the section on that page called "Browsing history" and click the "Delete" button.
Once clicked, there should be a list containing all the things your cache provides. What you may want to delete are the "Temporary Internet Files" and possibly "Cookies" for the cookies have a lit'le part in timed out sessions.
This should help your problem. ~
Chrome
On this browser, underneath your close button should be a mini wrench icon. Click on that to reveal a list of the tools.
Click on "Options", thus a new window opening titled Google Chrome Options. On that window should be three tabs, click the "Under the Hood" tab.
After that, locate the "Clear browsing data" and click it. Another window should open. Be sure you have the following items checked off:
✓ Clear browsing history
✓ Clear download history
✓ Empty the cache
✓ Delete cookies and other site data
After that, click on the "Clear browsing data", then click "Close" and the problem should be fixed. ~
Firefox
When using this browser, simply press Ctrl + Shift + Del on your keyboard. A window titled "Clear Private Data" should open up.
Check the box that says "Cache" as well as "Cookies" and press "Clear Private Data Now". Once fnished, you can close out of that, and then refresh the page.
I hope this works. If it does, then I'm glad to have helped. ~ c: Though if it doesn't, then I apologize greatly. Maybe someone else would have another solution?
