How do I get the views pager to display (after adding an view header)?
To save you wading through the comments which led to this answer, here it is in summary:

The problem was that the 2nd view included in the Header of the main view also had a pager on it.

Two solutions:


Views can cope with having more than one pager, with a bit extra config: you have to set the Pager Id field on one of the Views Displays to an integer not in use by other views/displays on that page (e.g. 1 instead of 0).
In my case I realised that the attached header view did not actually need a pager (it was only ever going to display one result - the description for the taxonomy term), and I should have selected "show fixed number of results" instead of a pager option. Changing this fixed the problem.


Hope this answer is useful for someone else getting stuck!
