[TYPO3] Changes in RSS feed template don't work

[Bing Du]

Hi,

typo3 4.0.6
tt_news 2.4.0

In my master template I have:

plugin.tt_news {
  displayXML {

      rss2_tmplFile = fileadmin/templates/typo3/tt_news_rss2.tmpl
      blah blah
  }
}

In fileadmin/templates/typo3/tt_news_rss2.tmpl, width and height were
commented out like this:

                        <!--
                        <width>###IMG_W###</width>
                        <height>###IMG_H###</height>
                        -->

But when I looked the source of http://www.somesite.some.edu/rss.xml (in
SeaMonkey web browser), both <width/> and <height/> are still there.

I cleared all the caches I could think of, clear all cache, clear FE
cache, clear page cache, clear cache in typo3conf/.  I also cleared my
browser's own cache. My changes in
fileadmin/templates/typo3/tt_news_rss2.tmpl just doesn't take effect.

Anybody know why?

Thanks in advance for any help.
