For anonymous OJS users: ui.js (which generates locale strings) is not available if allowed_hosts is not set

Issue

• Since OJS 3.4, the setting allowed_hosts is a mandatory field in the file config.inc.php.
• After OJS 3.4 , the following setting allowed_hosts = ‘[\’localhost\‘]’ is already included in the config.TEMPLATE.inc.php file , therefore it would not create an unauthorized error for not logged users.

If a server administrator moves an older config.file from an older installation prior to OJS 3.4, allowed_hosts = ‘’ or the correct host setting must be added to the config.inc.php file. Recommended is the exact host name as described in the `config.TEMPLATE.inc.php

@withanage, this is already included in the OJS 3.4 release notes; see: https://github.com/pkp/ojs/blob/main/docs/release-notes/README-3.4.0#L24
