Please upgrade to 2.1.x here.
The 2.0 branch is no longer being updated.
We are just about to start using Vanilla Forums for our schools internal staff forum and I have hit what I think should be our final stumbling block.
Everything is perfect but when trying to reorganise categories I get the error 'Oops...Didn't save properly'. Does anyone have any idea why this may be? I have tried giving full permissions to everyone on the entire Vanilla directory to see if it was a permissions issue but the error still appears.
If there is another was to reorder the categories I am happy to give that a go.
