Just my €0.02 as I got it working again with core150 here the steps taken as described in the bugtracker
- if not already done, disable location-block, methods in this thread
- upgrade, restart, login on shell
- run ‘location update’, take note that the version it gets is from tuesday at least
- restart
- enable location-block
- reload rules
- should be working again, if not login on shell, disable using above methods and wait patiently for final fix?
These steps worked for me, and I block all but two countries.
