[TYPO3-english] realurl defaultToHTMLsuffixOnPrev=1 not working

[Jennifer Koenig]

We're using TYPO3 6.2. Since we updated realurl from a 1.x.x version to the latest version 2.0.14, we no longer have ".html" and the end of our url path. What used to be like this:

mytheme/mypage.html

is now this.

mytheme/mypage/

Despite defaultToHTMLsuffixOnPrev=1 in the realurl configuration. Our Typoscript looks like this:

config {
..
simulateStaticDocuments = 0
baseURL = (our site)...
tx_realurl_enable = 1
config.defaultToHTMLsuffixOnPrev = 1
}

Does anyone have an idea what might be keeping the urls from ending with ".html"?
