No Devices

Anton:

Added device successfully and used for two days.
Now cannot see devices in Demo3.traccar.org .

Can advise how to solve this ?

Please try now. There are some problems with foreign keys on the third demo server. I would recommend to use one of the other servers.

Anton:
Thanks for the prompt attention.Working well at the moment.
Can recommend which 1 among the 4 demo server is best ?

I would recommend demo2 or demo4.

ok .Will migrate. Thanks for wonderful Support.
