Hi @Jvil
The error stating “… not allowed” means, you need to add your site URL to the allowed hosts config.inc.php
So, could you try to modify the allowed hosts line in your site’s config as the following?
; Restrict the list of allowed hosts to prevent HOST header injection.
; See docs/README.md for more details. The list should be JSON-formatted.
; An empty string indicates that all hosts should be trusted (not recommended!)
; Example:
; allowed_hosts = ‘[“myjournal.tld”, “anotherjournal.tld”, “mylibrary.tld”]’
allowed_hosts = ‘[“rac.sac.org.ar”, “www.rac.sac.org.ar”]’
Regarding “PHP Notice: Undefined index: stageId in …” notice, there are previous discussions that may help you
