hi carolina
I hope this syntax can help you ??

is_page(‘shop‘) || (is_single() && in_category(array(‘necklaces‘,’earrings‘)))

text in bold tag are case sensitive.
if your page name and categories are Shop, Earrings and Necklaces , you can try this conditional below:

is_page(‘Shop‘) || (is_single() && in_category(array(‘Necklaces‘,’Earrings‘)))

good day ??
try this, maybe it would help your problem

hide from specific pages and hide from all posts under the specific categories.

!is_page (array(6095,6096,7770)) || (is_single() && in_category(array(1,2,3)))

bold markup is an example of your related ID

hide on single post and archive

!is_single() && !is_archive()

hide on pages, archive and archived post page (your-site.com/page/x/)

!is_page() && !is_archive() && !is_paged()

hi friend ??
maybe you can try to replace
&& to ||

is_home() && !is_paged() || is_page(‘About’) || is_page(‘Contact’)

to display only at home and to all pages sidebar ( such as contact, about or disclaimer page)

is_home() || is_page()

5,9,10,11 are example of your category ID

sorry, edited typo: missing ‘)’ at end of logic

is_category(array(5,9,10,11)) || (is_single() && in_category(array(5,9,10,11)))

if post pages = your single post, Maybe you can try this logic ??

is_category(array(5,9,10,11)) || (is_single() && in_category(array(5,9,10,11))
