How to correctly modify .tpl files so that the changes are displayed on the site?

I am changing the templates files, but there have been no changes on the site. I tried to clean the template cache, reinstall ojs (3.1.2), but the result is the same.

hey @Eugene.B

Some templates are overridden in themes, so be sure that you’re editing the correct template.

Hey. I’m trying to edit the standard theme, on clean ojs.
For example, I try to edit templates/frontend/components/primaryNavMenu.tpl

search “child theme”
