Hello,

Thank you very much for your response and support.

I also appreciate your advice about checking the browser inspector — that was really helpful.
When I looked into it, I found that access to “/wp-admin/admin-ajax.php?td_theme_name=Newspaper&v=12.7.1” was returning a 403 error.

After some investigation, it turned out that the request was being blocked by the hosting provider’s WAF settings.

I’m sorry for the trouble caused due to my lack of initial investigation.
Thank you again for your assistance!
