Until they get it sorted (if ever!), the only way to see page 2 etc or answers is to manually modify the address (URL) in the address bar at the top of your browser.
EG
The ED's post in Suggestions currently has 22 answers and its address is:
http://www.theanswerbank.co.uk/Answerbank-Suggestions/Question804735.html
There, you will just see the first 20. Note that there is NO INDICATION on the page that there are in fact more answers to be seen.
To access page 2, you need to add a hyphen and a 2 after the question number and before the .html so it looks like this:
http://www.theanswerbank.co.uk/Answerbank-Suggestions/Question804735-2.html
and then press Enter/Return/Go or similar.
Of course, you will have to change the 2 to a 3 to see page 3 etc.
