The order of my categories have suddenly changed, although they are still the same in the settings, and I can't get them to go back to the order I would like them to be in.

To try and narrow-down what this problem could be, is everything as it ought to be, if you use the SMF default theme?
did you or your host recently do any changes your database?
/me seems to remember that change the position of one of them in the admin area (even if they are correct) and then put it back should fix the issue.
that is as long as the database table is not innoDB if it is that will do nothing.
I thought the problem with innodb was limited to boards. ???
I have to find the code again, I don't remember it any more.
i am not 100% sure but i believe that if the boards are not in order it can effect the categories as well.
but maybe the op is talking about boards and not categories... without the op giving more information it is hard to tell either way.
^^ This.
It's almost certainly in an InnoDB table now which means either a code change or a schema change.
This is a known issue that we have tracked on Github as must-fix for 2.1 and we'll need to find a suitable fix on a more permanent basis for 2.0 - https://github.com/SimpleMachines/SMF2.1/issues/887
Since it's tracked I'm going to close this topic.
