Hi, I browsed around both the support forum and the codex but couldn't find an answer therefore here I go:
Comments to POSTS work normally (some already commented, indeed) but comments to PAGES - although I checked the box "Allow Comments" in the editor window - do not work: it neither appears the link to comment at the bottom of the text.
Installed and activated plugins:
* Iimage Browser
* Post Teaser
(but I'm rather sure it's not their fault as it doesn't work even if I deactivate all of them).
