General Information

This issue only affects some 3rd party extensions in Joomla! versions 3.1.4 and higher

What is the cause

An instance of Joomla! Core using JBrowser has been removed causing it not to be automatically loaded on all pages.

How to fix

Change the source code to something similar as below.

From this:

$browser = JBrowser::getInstance();

To this (with legacy way to load classes):

JLoader::import('joomla.environment.browser') // Add this linecode
$browser = JBrowser::getInstance();
