I am experiencing issues on the web front-end (not admin) interface for a single user only. The other users', when logged in, do not have any issues navigating or using the web interface for mail, calendars, contacts, etc. After logging in, the interface is displayed. I can click on an email, and its contents appear in the right side. But, as soon as I click on a second/different email, the spinner appears and the entire system just hangs and will never respond to any further clicks or navigation. Images attached to show what I'm seeing. Eventually, the "Connection Problem, Could Not Connect to Your Server" error will appear at the top of the page. Then, the actual page will completely time out, giving a 404 server timeout error. However, other users logged in using the web interface at the same time, do not experience this issue. If I refresh the page, it comes back, and the entire cycle repeats itself. Any idea why only 1 user is experiencing this issue? What can I do to resolve this? Thanks!
