I'm currently using Joomla 1.6.5 and CB 1.4 with Groupjive 2.3 and Kunena 1.7.0 - these all work

I updated to J1.7.2 then I installed CB1.7.1.

I'm getting a Internal Server Error after installing com_comprofiler when I click panel configuation or users/tab/field. The other tabs work OK

SEF is ON
I do have an Akeeba Backup of the site.
Is it possible that a database field is causing this error?

[MOD EDIT]: Query log isn't necessary

I disabled system-SEF but problem persists. Yes, it is a 404 error

Steps taken:
Updated to J1.7.2
Uninstalled com_comprofiler
Installed CB1.7.1 com_comprofiler
Installed old ue_config.php in administrator/components/com_comprofiler
Went to save configuration (configuration tab) 404 ERROR - Internal Server Error or misconfiguration

additionally I went to TOOLS tab and under FIELDS database there was a misconfiguration. I click link to fix it which it did OK. All other tools worked OK.
