If you have encountered one of the display errors in Displayforce Manager (objects on the page are placed or displayed incorrectly or not displaying at all) then you should clear your browser's cache.
After clearing the cache your browser will load most recent versions of web-pages and programs.
Algorithm of clearing the cache in different browsers may vary, but in most cases the following actions are useful
1. Open your account in your browser and press F12 (or Ctrl+Shift+I , for MAC-users the combination is ⌥ + ⌘ + I) to open browser console
2. In console, on the Network tab check the "Disable cache" checkbox
3. Press F5 to reload the page.
If these actions did not resolve your problem - please contact Displayforce Customer Support specialists using one of the ways described HERE
