Morris Minor Owners Club

At the bottom of the cars for sale page there is an option to View topics from .... and then a drop down menu which gives you periods of time options, but it only seems to go back 1 month maximum, but there is an option for three months and longer, these don't seem to work.Am I doing something wrong?

There is an 'autoprune' set for 45 days in the cars for sale forum so ads older than that will be automatically removed.
