Can't disable .http suffix in page's address name

Regarding to best SEO practices, it's better to get rid of '.http' suffix in addresses.
I erased '.http' suffix in System - Content types - HTML. Saved configuration, cleaned cache (in MODX menu). But suffixes are still present.
I erased the core/cache directory from the disk, but every page still generates with .html prefix.
Is it a bug or something?

modx revo 2.2.10-pl

For your content type delete the file extension.

Thanks, but i did it already. It doesn't work. My entire message is about that issue.

If you removed the .html from the File Extensions field of the HTML type in Content Types, then cleared the cache, it should generate new links without the extension. Are you sure that the offending links are not hard-coded somewhere?

Links (page aliases) aren't harcoded (URIs aren't 'frozen')
I cleaned cache many times via MODX menu
I removed (rm) /core/cache dir twice
I created new page with new alias (somealias)
Whenever i open it - it keads to somealias.html

Thanks for keeping interested.

I don't know what to say. It always works for me. Are you sure this is what you've done in System -> Content Types?

Yes. That's what i did. Erased the '.html' suffix. Which version of MODX do you use ?

I've used Revo since 2.2.4, and now am using 2.2.10
