org-ref3 export html with references of pages

[Joseph Vidal-Rosset]

Hello everyone,

With org-ref (version 3) I meet the following (minor) problem with the
html export of references when I want to give the pages of a book in
numerical csl format.

With LaTeX export, no difficulty: I get

  [1, pp. 55-56]

to refer to the book 1 and pages 55-56.

With html export, I get only:

[1]

and no mean to give the pages in this format.

John Kitchin tried to help me (with downgrade to org-ref version 2), but
it is not so easy to downgrade and with regular org and prelude
upgrades, it is not easy always to keep the same version of org-mode.

Help is welcome, if someone knows the solution.

All the best,

Jo.
