[TYPO3] TemplaVoila: html template doesn't reflect changes?

[Bing Du]

Hi,

Typo3 V4.0.4
templavoila 1.1.1

The original html template used <iframe> to include an external html file
like this:

<div><iframe src="/fileadmin/templates/html/main/header.html"
width=....></iframe></div>

header.html has

<table>.....</table>

I replaced <iframe> with the actual content of the external html file.  So
the html template should be like

<div><table>...</table></div>

I've cleared all the caches that I can think of, 'clear all cache' in the
template function, clear FE cache and clear cache in typo3conf/, and I
also cleared my browser's (Firefox) cache.  But the page source of the
html template still has <iframe>.  Do I have to redo mapping to make the
changes in the html template take effect?

Thanks in advance,

Bing
