debug.txt in the TWiki data directory. Well behaved Plugins will have a debug flag turning on debugging. The core of TWiki has no debug output by default. It is turned on in different ways in different modules. Some have a writeDebug routine at the start that usually has the body commented out.
Debuggers such as PerlPtkdb can also be used.
