Regarding the too many redirects issue. I have spent some time looking into this.

First off, I cannot reproduce it. I am testing from outside of my own network, connecting via a 4g service provider, using Firefox and safari.

I have traced the route of URL requests and see only 2 redirect

Browsing to picbasic.co.uk you are redirected to picbasic.co.uk/forum
and then when using the forum you are directed to picbasic.co.uk/forum/

Browsing direct to picbasic.co.uk/forum will result in a redirect to picbasic.co.uk/forum/

Browsing to piucbasic.co.uk/forum/

results in no redirects.

as far as I understand, there must be somewhere a redirect from within the forum to picbasic.co.uk - which will then result in the redirect loop

I cannot find this at the moment - I will continue to look into this issue
