When troubleshooting problems with your Drupal site, you may want to try clearing the cache to see if that fixes the problem.
Additionally, your role in Drupal may not have the proper permissions to complete the task. Contact your site administrator for additional information.
Click Menu in the Administrator toolbar.
Click Configuration in the Menu toolbar.
Click Performance in the Development section.
Click Clear all caches.
Note: There are two levels of cache for your Drupal site: Drupal cache and Varnish cache. When you click Clear all caches, it only clears the Drupal cache, not the Varnish cache. When you are signed into a UMN Drupal site, you are seeing pages cached with Drupal Cache. Visitors to a UMN Drupal site are seeing pages cached with Varnish.
