Try clearing your memory cache in your browser. Are you by chance using Chrome for your browser? If so, try disabling your browser plugins.
I have the same issue.
Your advice does not help much. Trying in IE11, Chrome, Mozilla.
If you click "see more" the 404 error comes each time ever just right after clearing cache.
After you clear your cache did you restart the browser? If so and it doesn't resolve the issue then we may have a fix for this issue in a little while. I'll provide more information soon.
