I too was having this type of problem for a while - couldn't see reply buttons or get to private areas. I think I have sussed a way that works - though I certainly used not to need to do it this way.

Call up the Carers UK home page in the usual way. DO NOT log in yet.

Select the Forum link. You will see the forum board index, excluding the private areas, but will not be able to reply to anything.

NOW log in. You should have full access, including private areas and reply buttons.

This problem seems to have started a few months ago - before the "facelift", which did not cure the problem as I expected.

Give this a try - it has worked reliably for me the last few times. (If not, then I fear you will need to contact the forum administrator.)
