I'm working on a new cart (v1.38) and have added several modules (easy checkout, google tracking, shopping cart sidebox, ). I normally test after adding a module to make sure I haven't irreparably broken something, but in this case I didn't test until a couple of weeks later and am now not sure quite what I did. (gulp!) .... I used the debug tool and originally it was throwing errors about adsense. I don't remember why I thought I needed adsense, so I edited/removed all the adsense files. But still no joy.

Currently the debug file is reporting:
Cannot modify header information - headers already sent by (output started at /includes/languages/english.php:1401) in /includes/init_includes/init_templates.php on line 78.

Lines 75- 79 are:
/**

* The actual template directory to use

*/

Does anyone have a clue for me?
