Log file ERRORs but no URI, Controller, Model or View details

I managed to fix this errors thanks to gadelet and RobertSF:

First error:

PHP Code:

ERROR - 09:33:46 --> Query error: 
 Undeclared variable: As_I_Mature - Invalid query: 
 SELECT id, title, xrl, memo 
 FROM wisdom ORDER BY title  
 LIMIT As_I_Mature, 11.html 


The Database error was in ./config/routes.php. Before upgrading to CI RC3, /(:any) was used extensively. Unfortunately I changed /(:any) to the incorrect /(:+) instead of /(.+) which resulted in incorrect URI parameters being passed to the Controller and Model.



Second error:

PHP Code:

ERROR - 12:03:59 --> Severity: Warning --> ini_set(): 
 A session is active. 
 You cannot change the session module's ini settings at this time 
 /my/system/folder/ci3/CodeIgniter-3-0rc3/system/libraries/Session/Session.php 317 


 I amended and added the following lines to:
   /my/system/folder/ci3/CodeIgniter-3-0rc3/system/libraries/Session/Session.php 317
// Line: 143 - ORIGINAL SCRIPT
// session_start();

// John_Betong added to try and see where the session_start() was already started
if( ! isset($_SESSION) ):
   session_start();
   log_message('error', 'Session ALREADY STARTED: ' .$this->uri->uri_string());
else:
   session_start();
endif;

This error has not occurred since so it looks as though the error could have been cleared with fixing the first error.
