Entire site is a blank page after upgrade

I just did a routine upgrade to Discourse using the web UI.

Now, only the site background is visible. Here is to URL to our site:

I tried rebuilding using ./launcher rebuild app

I also tried restoring from the latest backup, which I created right before upgrading Discourse. I used these instructions:

I also tried using safe mode, which just sends me to the same login url and blank page.

I’m not sure what else to try now. Our forum is completely unusable for now… Any ideas? I’m stuck! :cry:

Try going directly to this URL:


The normal method of entering safe-mode seems to be broken on your site.

I think you will be able to login from that URL. Once you have logged in, go to your Admin / Customize page, enable the Default Discourse theme and remove all theme components from that theme. If that works, you can then try to figure out what is causing the issue. I’m guessing it’s your site’s theme, or a theme component.


Thank you @simon, this worked!

I used your safe mode url, which allowed me to log in.

Then I got back to a blank page, but I was then able to use the normal safe mode url to access the site.

I went to Admin / Customize and disabled a component, and no more blank page. So I guess something is up with that component.

Thanks for your quick reply on this. I’m so grateful that I am able to get our forum working again while I figure out what is going on with that component.
