I noticed some irregularities working here at News II, especially with the GK Menu. When I posted, deleted or configured menu items at the Main Menu, it won't immediately delivers result at the frontend when latter is refreshed. I'm using Mozilla Firefox. Is this issue related with the browser, or was that the previous data are actively stored in any temp locations that are usually being retrieved first by the browser instead of the updated data from the database?
Kindly give some explanation. Please help.
