What log file should I look at to determine why a restore isn't working?

Hi,

I’m trying to migrate from a Trixbox system to a PBX-In-A-Flash system. I performed a FreePBX backup on the Trixbox system, transferred the file to the PBIF system, set the permissions on the file, but after I restore and click the red bar, none of the extensions, trunks, etc. appear in the GUI.

What log file can I look at to see if there are any errors? Thanks in advance.
