i am using an acer 7 chromebook and today when i go to my comcast logon site XFINITY by Comcast -- Official Customer Site | Email | Watch TV Online, i can sign on, but when i go to open an email, it just goes back to a new home screen for comcast; i have using this site on the chromebook for months with no problems and can open my email on another laptop with no difficulties - any ideas about what to do? thanks
Try clearing the cache.
Go to your Chromebook settings -> Show advanced settings -> Clear browsing data
Deselect all except "Cached images and files".
Usually this helps when there's an issue with a website you visit a lot.
