Commerce Bug in Magento CE 1.6
Quick note for all you Commerce Bug users. The core team made some changes in 1.6 that require you to tweak a configuration setting for Commerce Bug to work. You’ll need to go to
System -> Configuration -> Developer -> Template Settings
and set the Allow Symlinks value to Yes

Commerce Bug doesn’t use symlinks, but it does do a little jiggery pokery that allows its templates to be stored in the Commerce Bug module folder instead of of the app/design/* folder.
Just flip this bit and you’ll be back to debugging in no time! Readers of No Frills Magento Layout will want to beware as well, as some of the default modules use the same technique.
