Edit:
Still having the same error, am I the only person here who gets this? Edit 2:
Now I really want to update something in my topic, because I found a big problem in what I published there. Now I could fix it, but this error keeps coming…
Maybe you can check what request fails using your built-in browser debugging tools (press F12)?
You’ll be able to see all requests and when they fail (500 error) they’ll be marked in a red font.
If you click on the requests you’ll be able to see the details like hosts/paths it’s requesting.
Providing some extra information about the request that fails using the debugging tools will help troubleshooting it.
I get it when I click “Save Edit”, so basically in the same situation where the others get the same error, but retrying doesn’t solve the problem for me…
I have other reports about HTTP 500 and there is a critical Discourse fix available - I will install it tomorrow morning (when there is less traffic than now in the evening). Let’s see, maybe it resolves such issues!
I figured out the part of my topic which triggered the error:
It was only and alone the tag “androidapp”.
I have no idea why especially this tag but I tried changing every single part of my topic and this is the only thing that worked for me.
I also tried to delete just this tag, publish the edit and then adding it again, but then the error occurs, if I want to save the edit where I add the tag again, so replacing it worked well!
