The usual culprit for socket.io issues is usually not having sticky sessions. Socket.io requires sticky sessions so requests from a client always go to the same backends.
Custom email header / footer
I'm trying to add a custom header and footer to e-mails templates in the ACP, I have changed the partial, and tried to add to another template using:
<!-- IMPORT emails/partials/header.tpl -->
at the top of the template in ACP, but when I send the test e-mail the header is the default one, not the one I've changed, how can I customize the header and footer from the ACP? and not losing the content when I update the forum, should I create a custom file and add to that folder, or I am not using the correct template when I'm importing?
Sorry for the very late reply @julian !
yes I was rebuilding the templates, it was a misconception by my side, i thought that I could change on the ACP the header and footer and it will affect to the other templates, but i was importing the src template.
Now i'll try to override the e-mail templates using my child theme, is it just create a e-mail folder inside my templates folder?
i've seen that this has been asked before, but why can't you change the e-mail subject from the ACP? i had to modify it on the src template.
Thank you very much!!
