Hi Daniel
The data entry is a bit special as it using what is called
"application cache" in order to function offline. This means that all
files required to run this module is downloaded and cached bu the
browser. This makes it vulnerable to outdated caches. I think this is
reason for your problem. Maybe you logged in initially as a
less-privileged user, got the browser to download all files including
the menu, then logged in as a more privileged user. Can you check if
this is right by using the chrome browser, go to
chrome://appcache-internals/
and "remove" all application cache. Then log in to DHIS again.
