Expression always true

There is expression in file CRM/Report/Form/Instance.php:

$config->userFramework != 'Joomla' || $config->userFramework != 'WordPress'

but it always true.

if $config->userFramework is 'Joomla' then expression ($config->userFramework != 'WordPress') is true, so whole expression is true.

if $config->userFramework is 'WordPress' then expression ($config->userFramework != 'Joomla') is true, so whole expression is true.

if $config->userFramework is 'someOtherCMS' then expression ($config->userFramework != 'Joomla') is true, so whole expression is true.

Probably you should use operator "&&" instead of "||"
