Solution to invalid joomla background management menu

Joomla1.5.17 official version is installed in XAMPP environment. After the installation is successful, everything works normally. After the feature is disabled, you can access the management background. All the drop-down menus in the upper row are invalid. After searching for a long time, you can find the problem. The solution is as follows:

1. Check the name of the background directory, whether "Administrator" is written as "Administrator", or the access path is written as administrator, which should be http: // localhost/joomla/administrator .)

2. Check the permissions of the media folder under the joomla root directory and set it to 775.

3. Check whether the files in the media folder are complete. You can upload the media folder again.
