Hi everyone, I’m facing a critical issue with my Discourse community and would really appreciate any help or advice you can provide. When trying to access any post, I see the error message: “Sorry, we couldn’t load that topic. This may be due to a connection issue. Please retry or contact us if the problem persists.” :sob: :sob: In the browser’s developer console, I also get a 500 error with the following response: Failed to load resource: the server responded with a status of 500 () {"status":500,"error":"Internal Server Error"}. An example of an affected URL is: https://starorigin.net/t/topic/352/1. Here’s what I’ve tried so far: I reinstalled Discourse from scratch, and the new community worked perfectly without any issues. However, after restoring my backup, the homepage loads fine, but every single post returns a 500 error when accessed. I also tried migrating to a new server, but the problem persists after restoring the backup. I suspect that my backups might be corrupted, but I’m not entirely sure. To test this, I restored three different backups (from January 25, January 23, and January 6), and all of them resulted in the same 500 error after restoration. This is very confusing, as I don’t know what could have caused this issue across multiple backups. Has anyone encountered a similar issue after restoring a backup? I’m currently stuck and unable to restore my community to full functionality, so any guidance or suggestions would be greatly appreciated. Thank you in advance for your help! :sob:

I tried creating a new post, but after publishing it, the new post also failed to open and displayed the same error. :sob:

Do you have any plugins installed? Do you have the same plugins installed on the new system that you did on the one that made the backup?

Yes, the plugins should be the same. I copied the app.yml file from the old server to the new one, so the configurations are identical.

I have pinpointed the issue, and it is the AI plugin that is causing this problem.

Right. I think I’d mostly figured that out for someone else yesterday but didn’t get far enough to know it was a bug
