Restore causes blank GUI

Primary server is running in user/device mode built like:

AsteriskNOW 1.7.1 installed option 1
yum update
yum shell
remove asterisk16 asterisk16-core
install asterisk18-core asterisk
ts solve
ts run
upgrade FreePBX from 2.7 to 2.8

Secondary server built identical.

Run full backup on Primary server.
SCP it to secondary server.

When I go to restore on secondary server it starts the restore and in a minute or two goes to blank screen.

restart amportal or reboot the server comes right back to the same place.

Check to see if the php has DB access. Try running pear install DB on the system you’re restoring. Then, if the gui is still sketchy, try amportal restart and check the GUI again.

Thank you for the suggestion. Unfortunately it did not help. Says already installed, No valid packages found, install failed.

What do the logs show? amportal a dbug

I was testing with in a virtual machine of the secondary. Found that my VM was 32bit and live host was 64bit. The digiumaddoninstaller was causing the backup to not be able to be restored in a different version.
