I can’t believe I’ve missed that. I’ve removed the ‘page’ div. Thanks Jason and Ov3rfly!
That put me on the right track, thanks. Disabling all other plugins made the problem disappear, so re-enabeling them one by one soon pointed to the ‘guilty’ plugin, in this case FormForAll.
Thanks for your quick and helpful reply, I really appreciate it!
I am very interested in the answer as well. With a lot of pages, displaying 20 per page is not very handy. Of course there is the page search function, but then you loose track of the hierarchy.
Anyone?
