For some reason the settings on this site changed yesterday so I now see only 30 posts per page (the forum default) instead of 40.

I have been on to settings and changed it back to 40 from the default (of 30) and saved the change - and repeated and repeated - but I still only get 30 to a page. The settings change will not apply!

Any ideas?

It's not a big deal but I am used to 40 per page and would prefer to get back to that.
