I've added the plugin and the API key, but no-one gets any emails from my forum. I've followed the instructions multiple times, restarted several times and used the API key via cURL to confirm it works (copied and pasted it out of nodeBB to be sure it's the same), which it does.

Trawling through the startup logs, I can see

2024-10-27T15:53:38.103Z [4567/12061] - info: [plugins/emailer-sendgrid] Custom field nodebb_username already exists, OK.
2024-10-27T15:53:38.162Z [4567/12061] - info: [plugins/emailer-sendgrid] Custom field nodebb_fullname already exists, OK.
2024-10-27T15:53:38.162Z [4567/12061] - info: [plugins/emailer-sendgrid] Done.

so that looks good. If I go to the events, I can see:

{
    "confirm_code": "[confirm code]",
    "email": "[user's email]",
    "force": true,
    "timestamp": 1730038787173
}

so that looks good too. I've been through the source code for the plugin and I can see where Winston would log something out if there was an issue, but there's nothing in the logs - after all the SASS deprecation warnings, nothing else gets posted. I've enabled port 1337 on my server's firewall to ensure the connections stay alive, in case that's relevant.

Do I need to open port 25 for SMTP? Thanks!

Would it be possible to add a line calling that out explicitly in https://docs.nodebb.org/configuring/config to make it obvious to stupid people like me?

Nope, a build isn't sufficient - it needs a restart too. Thanks for this! It's up and running now

I'm running ./nodebb build after the changes. Would that do it?

I've just set up a NodeBB installation, and originally I just put my site's base URL (https://drrelling.dev) as the URL during installation. I'm hosting it on nginx on a subfolder via proxy_pass, however, so I've updated the url property in config.json to https://drrelling.dev/forum. The page loads on /forum, but all the asset files are still referring to the base URL and so are trying use https://drrelling.dev/assets/ as the assets folder. Opening one in a new tab and manually editing the url to be https://drrelling.dev/forum/assets/ shows the expected file.

Poking around in the code I found the config.relative_path attribute, and sure enough when I checked the config in the browser it was set to "". Is NodeBB having trouble parsing my weird URL, or is there something else I'm doing wrong?

Thanks!
