Helo and thanks for your help.
I am trying to install the WHMCS widget and it seems so straightforward but it is not working - it simply doesn't show up in the Administrator Roles under widgets - or anywhere else on the permissions page.
When I look at the instructions in the wiki it shows that the folder was put into the main 'members'(WHMCS) dir and then magically appears and I have done that.
Any help appreciated.
