Good morning,

Discourse version 3.1.0.beta4  
I’m trying to reorder the categories from the UI and when I press save order I get a 422 error. Interesting fact: my categories on the main Discourse page doesn’t have the same order on the reorder categories page.  
Example : I have the supervisor category at position 4 on my main page, on the other hand when I go on the reorder categories page, the supervisor category is not at position 4, but at position 23 and if I press on save , it will go to position 23 as shown in the reorder categories page. I have the 422 error that appears, but there are still changes that have taken place.  
Last week I had no problems with the reorganization, I only had this problem when I moved the new category my script created today to the first position.  
In the preview page of Chrome I have a little more details about the error:  
The change you wanted was rejected. Maybe you tried to change something you didn’t have access to.

I’m admin, so I shouldn’t get this error.  
In the source code I have this exception that throws :  
SyntaxError: Unexpected token ‘\<’ "\<!DOCTYPE "… is not a valid JSON

I’ve:  
Done a server reboot  
Enabled Allow Uncategorized Topic option

Do you have an idea what I could do ?
