The massaction sendEmail feature added to this page for v24 by 8f0b7e3f
(#37937) reads $conf->invoice->dir_output and includes
core/actions_massactions.inc.php on every page load. When the invoice
module is disabled, dir_output is empty, so the include hits its
protection ('$objectclass or $uploaddir was not defined') and exits.
The referers tab built by product_prepare_head() links to this page
unconditionally, so any v24 install without the invoice module gets a
fatal error on the product referers tab. In 23.0 the page had no mass
action code and rendered fine without the module.
Make the whole massaction machinery conditional on isModEnabled('invoice'):
do not read dir_output, do not propose the mass action, neutralize
$massaction and skip the actions_massactions include when the module is
off. This restores the 23.0 behavior for installs without the invoice
module and changes nothing when the module is enabled.
