Server error - 502 - ok

[N3R1]

On my on HOSTED system there was un update do be done. I did a back up and then updated.
Since it was done i cannot log in anymore and the phones are down.
When I try to log in a get "Server Error" and if i try to recover my password 502 - ok
I cannot recover the back up since I cannot log into the consolle.
What can I do to us the back up?

Hi
I think you need to reinstall previous V18 release with help of your backup to restore pbx as it was.
I hope you have backups stored out of PBX itself

You probably missed the prerequisite to apply BEFORE V20 migration.
