Local server will not work above version 0.15.3

Hi
My Phone updated the client today and now I have an issue with the server version being out of date.
I have downloaded the latest version but the app cannot find the server. Using the web admin page any version above 0.15.3 has either a empty or missing user (I assume this is way it does not work)

Any and all ideas are welcome to help resolve this issue If all else fails I will have to go back to the older client on my phone (Android)

Many thanks

Jman
