We publish new issues online with the same frequency as the print
edition. If you know that a new issue of the print journal has been
published but don't see that issue appearing on the site you may be
experiencing a caching problem.
The most likely source of this caching problem is your own
computer. To remove the out-of-date pages from your cache you should clear
the cache manually.
After clearing the cache you should quit your browser, restart it and
return to the bmj.com home page. If you still see the incorrect date
reload the page several times.
If these steps fail to remove the outdated page, this would suggest that
your internet traffic may be going through a proxy server which is failing to
update itself properly. Unfortunately, you'll need to speak with your
Internet Service Provider to resolve this problem.
