Hello James,
Welcome to AllStar. On the stats page problem; first be sure your node shows on the Nodes List with a green background on you node number. If not, you’re node is not registered and you’ll need to work on that first. Second, be sure the two lines in rpt.conf to post to stats server are uncommented. Some AllStar versions have a menu setting to enable stats.
On the Webtransceiver; That’s unlikely to ever work because Java is not supported on any modern web browser. However, there is one browser called Pale Moon which some people have made work. Have a look at this wiki page for more details. The Webtransceiver was never stable so even if you do get it working don’t expect much.
An alternative to the Webtransceiver is Zoiper, a mobile app. Have a look a this post for more information.
Let us know if you have any questions and how it goes.
