Long post…

A couple of days ago I migrated my forum to a new server. The migration went well and users were able to log in and use it as normal. However, after 2-3 hours logged in users found that they were unable to use it. I didn’t see the problem initially, but within 10-15 minutes I found my account was affected too. What I was seeing was the forum page being repeatedly output down the page but with the content missing…so header…bit of text…header again…bit of text again…header again…etc

I assumed something had gone wrong with the migration so as there were very few posts since the migration and I still had the old server available, I just fired up the forum on the old server and pointed DNS back to that. That would give me time to figure out what went wrong and try the migration again.

Then today, my ‘old’ forum prompted me to say there were critical updates needed. I applied them and things seemed to be OK. However, an hour or two later and the old forum is now exhibiting the same weird display problem that my migrated forum exhibited.

So now I’m thinking that there’s something wrong after the upgrade. The migrated server would have picked up the latest code when built, so it exhibited the problem straight away. The old forum only got the updates today and started to go ‘haywire’ soon after.

So far I’ve unsuccessfully tried:

1. ./launcher rebuild app
2. Comment out all the plugins in app.yml and ./launcher rebuild app
3. Running in [safe mode](https://meta.discourse.org/t/53504?silent=true) with all options turned on
4. Clearing browser cache
5. Tried different browsers (Chrome, Edge, Forefox and Opera)

The problem seems to be progressive for logged in users. I logged in with a test account today and that didn’t exhibit the problem, but when I tried that on the migrated server the test account eventually showed the same problems. Unfortunately I’m unable to try anything more at the moment because my admin account is showing the problem so it’s unusable.

I have a backup from before the upgrade, but I suspect that’s not going to help. If I rebuild the forum it’s going to pick the latest updates so if I restore the content into that it’s probably going to go haywire again within a few hours.

Server setup:

Debian 12 running Docker Swarm v26.1.4. 120GB of disk space available. 64GB RAM with only about 20GB currently in use. Connections in to the server are over Cloudflare Tunnels. The old server has less available disk space and memory, but neither are maxed out.

I’m trying to think what else I can do now to try to get things back online. I’m open to suggestions!
