[SOLVED] Internal Server Error

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

Please disable SEF and confirm if issue persists. I don't see anything in your server error log pointing to a problem. What is the exact error you're seeing? 404?

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.

DEBUG:
CB FIELDS

[MOD EDIT]: Query log is not necessary, please don't provide it unless explicitly asked as it expands thread significantly making it difficult to review.

Are you using Joomla SEF or 3rd party SEF? Was the htaccess default rewrite rules altered or still default?
