J3.x:Missing JBrowser class after upgrading
From Joomla! Documentation
General Information
This issue only affects some 3rd party extensions in Joomla! versions 3.1.4 and 3.1.5
Tipical error message
Fatal error: Class 'JBrowser' not found in path/to/file.php on line XY
Afected versions
After update to Joomla 3.1.4, some some extensions that depend on the native autoloader , with a working code before, may stop working.
Workaround
While this is not resolved, change the source code from something similar to this
$browser = JBrowser::getInstance();
//...
To this (with legacy way to load classes)
jimport ('joomla.environment.browser'); // Add this linecode
$browser = JBrowser::getInstance();
//...
