how to fix the path?

how to fix the path, so that the theme is displayed, does it cause anything else not to work properly?

easiest way

What is repair_settings.php?

[Kindred]

basically, your theme directories are not correctly set...   use repair_settings.php
and then, in smf admin, go to the themes settings and correctly set the theme paths and urls

and then, in smf admin, go to the themes settings and correctly set the theme paths and urls

you dont need to do that, repair_settings.php will fix all themes that are installed.

it's always safer to CHECK and CONFIRM in the admin, even after running repair_settings.php
