General Information

This pertains only to Joomla! version(s):- 3.1.4  3.1.5


What is the cause

There were CSS changes to the administration template and your browser is storing the out-dated version to speed up site loading. After performing an update it is ESSENTIAL to clear your web browser cache to reload the admin template CSS.

How to fix

Common

Refreshing the browser cache solves this immediately. If you do not refresh the browser's cache, you will not see the toolbar buttons until the new CSS file replaces the CSS file in the browser's cache(temporary internet files).

Here is how to clear a browser's cache by browser:

  • Firefox / Safari: Hold Shift while clicking Reload, or press either Ctrl-F5 or Ctrl-R (⌘-R on a Mac)
  • Google Chrome: Press Ctrl-Shift-R (⌘-Shift-R on a Mac)
  • Internet Explorer: Hold Ctrl while clicking Refresh, or press Ctrl-F5
  • Opera: Clear the cache in Tools → Preferences

Not common

If the problem persists you may want to check to see if your server has mod_pagespeed from Google enabled. If it does, and you want to keep using mod_pagespeed you'll need to flush the server side cache on upgrading to 3.1.x. You do this by logging into the server and then executing

A typical command and location:

sudo touch /var/cache/mod_pagespeed/cache.flush
