Sent messages not show

I install the version 1.3 of playsms on linux centos 7. everything is ok in installation.
when i send an sms it is not in queue list either my sent list.
i have checked the database and i see it is in the queue table with the flag of 3. i don’t know the flag mean and i really dont know what to do with this and how to debug it.

Did you do the additional step?
