About "/var/lib/asterisk/bin/retrieve_conf "

after i add extension, i must run /var/lib/asterisk/bin/retrieve_conf , and then click the red bar to apply configure change.
I think the operation style is not convenient.
I just want to click the red bar to apply configure change and i think freepbx can do,aren’t?
maybe configure asterisk by using freepbx, must run /var/lib/asterisk/bin/retrieve_conf before click the red bar, isn’t?

No that cmd I gave you was just to see if MYsql is working right .

You have other issues which you need to trouble shoot.

Making changes means clicking the red bar and the next popup window
to apply those changes
