Original GitHub issue: https://github.com/benbusby/whoogle-search/issues/507

Clicking a NoJS Link on my private instance results in an Internal server error. I know this CAN work as it's working on one of your listed public instances( which allowed config changes to enable the NoJS). The error:

  File "/home/whoogle/whoogle-search/app/templates/display.html", line 39, in top-level template code
    <a id="gh-link" href="https://github.com/benbusby/whoogle-search">{{ translation['github-link'] }}</a>
  File "/home/whoogle/whoogle-search/venv/lib/python3.9/site-packages/jinja2/environment.py", line 452, in getitem
    return obj[argument]
jinja2.exceptions.UndefinedError: 'translation' is undefined

If I edit the offending part of display.html to <a id="gh-link" href="https://github.com/benbusby/whoogle-search">View on GitHub</a> ,removing the translation, it works.

To Reproduce
Steps to reproduce the behavior:

Do a search
Click a NoJS Link
See error

Deployment Method
Manual
Clean, just reinstalled
Nginx proxy
debian 11 on a vps.

Version of Whoogle Search
GitHub

Additional context
This has never worked for me for as long as I can remember. But I only took a look today after playing with #276
I suspect it's maybe related to the deployment method but IDK ?
No big deal for me but I thought I should let you know.

My Nginx conf

server {
    server_name whoogle.domain;
	root /var/www/whoogle;
    access_log /dev/null;
	error_log /dev/null;
	index index.html index.htm;
	
	location / {
		proxy_pass http://127.0.0.1:5000/;
		proxy_set_header X-Forwarded-For $remote_addr;
}
	
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/whoogle.domain/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/whoogle.domain/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
  server {
    if ($host = whoogle.domain) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    server_name whoogle.domain;
    listen 80;
    return 404; # managed by Certbot
}
