Unfortunately that was not possible add module on Payplans page now.

So I can’t add them to any module positions within PayPlans but is it possible to publish modules to my normal template positions on this particular page? I’m not sure what page the confirm invoice is associated with.

Thanks!

Hey Greg,

Hm, generally modules are associated with menu items and it becomes tricky since PayPlans doesn't render it's own module positions on their pages.

Perhaps you would need to add a hack in your template to render a special module position when it is on PayPlans page. It could be something like this,

[gist]
<?php if (JRequest::getVar('option') == 'com_payplans') { ?>
<jdoc:include type="modules" name="position-payplans" style="none" />
<?php } ?>
[/gist]

We will try to add our own module positions in the upcoming major release of PayPlans 3.7
