• Can use please try with in_category('admission-event') instead of is_category('admission-event'); – Gopala krishnan Commented Dec 2, 2019 at 10:15

• Have you got solution for that? – Gopala krishnan Commented Dec 3, 2019 at 10:28

1 Answer 1

is_category() is the wrong function to use here. That category is checking Are we on the archive page for the given category?

The correct function to use would be has_category(), which is checking Is this post in the given category?
