Pankaj,
You have responded showing me how to turn off error reporting. I obviously turned it on to provide you the error - thus I know how to turn it off (and this is not the issue). I am confused why responded with this and disregarded the reason for this post.
There should be no error.
The issue is that the core Joomla function of placing custom field and field group tags inside an article is not working. It is not working because the Joomlart template override for article does not include support for them and it should. This is the issue.
Kindly, please report it to the devs and respond with a solution for the current and a hopeful update to JA layout overrides moving forward.
Thanks
