Dashboard Widgets Order Doesn't work

I have followed the instructions step by step but it doesn’t seem to work. I found a 4 year old post that said to comment out line 52 but that line is already commented out so I tried line 51 but that didn’t work either. I tried it with an old site and a new one created after the edits but no go.

Also the instructions aren’t very clear on the file page itself it says:

// Change this if you update the widget order and want all users to have

// the new order instead of just new users.

// Note that this will overwrite the custom widget order users have

// configured.

It says “Change THIS” what exactly is “THIS” ?
