Customizing search.tpl does not works as expected

i’m developing my custom theme for ojs3.
I’m able to rewrite all .tpl file (index, article, issue, login, menu ecc…) except for search.tpl

if i go to http://localhost:8080/ojs3/index.php/pro/search/search i lost all my css in header.tpl because it takes from /ojs3/templates/frontend/… and not from /ojs3/plugins/theme/mytheme/frontend…

Does anyone know why?

(i cleared all caches also)

Ok, maybe i’ve found the problem: the root of ojs site isn’t directly under www but www/ojs
