maybe.. Architect's problem is not in the template itself, but near the code that eval the template you checked.

You can debug it:

instead of run
[code=php]
eval('$output = "' . fetch_template('TEMPLATE-NAME') . '";');
[/code]

try
[code=php]
eval('$output = "' . fetch_template('TEMPLATE-NAME') . '";');
echo $output;
exit;
[/code]

Check the output in your browser, go to line 33 and there are a lot of probabilities you will find an error in the php code.
It's not on line 33? look around... ;-)
