My upgrades page is completely blank.
I did ./launcher rebuild app and managed to upgrade to v2.6.0beta4, but even afterward, the upgrades page is blank. The <body> tag for the page is:
<body class="highlighter-context">
</body>
Any suggestions?
Can you share a link to your site?
It’s a closed forum. Happy to share but I figure that makes a difference, yeah?
I recommend you remove all third party plugins and rebuild. Also try safe mode see:
Thanks. I got some time to try these. Various options in safe mode didn’t help. Disabling all third-party plugins and including only docker_manager also didn’t change anything. Still a blank white screen.
I saw a post with the same issue from earlier this year, but the OP stopped responding, so no obvious cause or resolution.
I recommend posting a sanitized version of your app.yml … it will help us figure out what is wrong.
Okay, here you go:

ok… step one I recommend here is rebuilding this thing without any third party plugins. Only keep ones that are /discourse/discourse
Then if that works you can bisect to find out which plugin is causing the trouble.
Well, docker_manage plugin is not a discourse/discourse path, but with it disabled, ...admin/upgrade page doesn’t exist.
Enabling only the docker_manage plugin results in the same blank upgrades page.
Sorry, you’re right, I must have been hallucinating. Scratch that, it is in the discourse/ path.
But anyway, still a blank white screen.
With the availability of 2.6.0.beta5 (I’m on 2.6.0.beta4), I’m still running into a blank upgrades page. I’d be grateful for any further advice, since I’ve tried disabling plugins to no avail.
Have a look at chrome dev tools, are there any errors in the console when the page is white? My guess is that this is something to do with your CSP.
Thank you, you’re right—it’s refusing to load a script coming through my CDN. With url’s sanitized:
upgrade:1 Refused to load the script 'https://cdn-to-discourse.b-cdn.net/assets/docker-manager-app-32418f2f7cd50e6f4a0b8d13badc4e59f6a1ad74e7bed270f3a051478fed773d.js' because it violates the following Content Security Policy directive: "script-src https://forum.example.com/logs/ https://forum.example.com/sidekiq/ https://forum.example.com/mini-profiler-resources/ https://cdn-to-s3.b-cdn.net/assets/ https://cdn-to-s3.b-cdn.net/brotli_asset/ https://forum.example.com/extra-locales/ https://cdn-to-discourse.b-cdn.net/highlight-js/ https://cdn-to-discourse.b-cdn.net/javascripts/ https://cdn-to-discourse.b-cdn.net/plugins/ https://cdn-to-discourse.b-cdn.net/theme-javascripts/ https://cdn-to-discourse.b-cdn.net/svg-sprite/ https://matomo.example.com". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.
The Security settings page says “The current host and CDN are included by default.” Should I manually add the CDN to the whitelist anyway?
I see that an identical issue was brought up here, without a final answer about why the default whitelisting wasn’t working.
Hello,
I think you should add this url to admin CSP setting (content security policy script src):
https://cdn-to-discourse.b-cdn.net/assets/
And after check again the chrome dev tools errors.
Yes that works. I’m curious why the default whitelisting is not doing this automatically, though.
I am curious as well, how is your CDN configured? We may be missing some magic from docker-manager plugin.
cc @pmusaraj
Yes, indeed, we were. The docker_manager plugin was loading two JS files in a template using javascript_include_tag, which isn’t aware of DISCOURSE_S3_CDN_URL so it was defaulting to DISCOURSE_CDN_URL and tripping up the CSP.
Should be fixed now via FIX: blank upgrade page when using S3 CDN and CSP · discourse/docker_manager@3d37fd6 · GitHub
@paulrudy if you update the docker_manager plugin, you should no longer need to manually add https://cdn-to-discourse.b-cdn.net/assets/ to your CSP.
