[TYPO3-english] shared extensions issue

[tom liu]

Hi,

There are some typo3 sites. They have same extensions installed. I tried to
edit  public_html/*first/*typo3conf/ext/ajax_search/res/template.html, But
I found the others (such as
public_html/*second*/typo3conf/ext/ajax_search/res/template.html...)all
changed, So I think all these sites(first, second...) somehow are connected
to each other. If you change extension on first, second and the others will
be also changed.
So I wonder if I only want to change extensions on first, but not on other
sites(second...), how could I do?

Tom
