I am fairly new to Apex Development and am trying to debug some code developed by a senior level developer.
The code is a controller extension that errors with a SOQL limit without completing so the page is not completed.

I added system.debug statements to some of the methods in the code, turned on debug for my user and many different levels of debug but my system.debug statements fail to appear in the debug logs.  Based on other detailed entries in the debug log I have confirmed that the code where I've added system.debug is being executed.

Any suggestions?   I'm probably making a very simple/common beginner mistake.

Thanks
Debra
