Simple Template System: Problem

[Site-Evolution]

The have installed the Simple Template System (STS) mod on a clean clean OSC 2.2MS2. I have also installed an existing database form another OSC installation.

 

I have noticed several errors since the installation of both the STS and database.

 

1.MyAccount link returns the following error:

 

Warning: Cannot modify header information - headers already sent by (output started at /data/members/paid/w/e/******.***/htdocs/demo/*********/catalog/includes/languages/english.php:334) in /data/members/paid/w/e/******.****/htdocs/demo/********/catalog/includes/functions/general.php on line 29

 

********* = My domain name which I have removed.

 

2.Same error for the account link.

3.Click to enlarge returns my template.html with all tables removed, but no image!

 

This error does not appear for cart contents.

 

I would guess these errors are all a result of installing the template system.

Does anyone have any suggestion for how to fix these errors?

 

Many thanks
