OPAC search and menu toggles may fail to load on custom themes

Custom themes may fail to load essential JavaScript files, breaking search and menu toggles.

Pending AMI release

Overview

Customers using custom themes in their Koha OPAC may experience issues with the search bar and mobile menu toggles not functioning correctly. This is due to missing or incorrectly loaded JavaScript files in certain themes. The problem arises when the Asset.js plugin fails to resolve paths to the current theme’s JavaScript directory, resulting in silent failures where no script is loaded. This advisory addresses these regressions by hardcoding the paths to essential JavaScript files and ensuring they are correctly loaded in all themes.
