There is a problem using some browsers - certainly IE and Google Chrome that doesn't load the pages correctly.
Do not adjust your PCs - as I have spend the last 2 hours doing.
There a general forum host problem with a sub hosting called 'illiweb' that provides the GUIs for the pages.
You may see empty/broken boxes and lots of '????'.
The host company is dealing with it.
You can still use the forum but some guess work maybe required....!
