Conflict with dsIDXpress plugin

Hi,

I get a “Cannot Modify Header Output” error when I have Intuitive Post Types Order and dsIDXpress running together. Same thing happens if I use the Post Type Order plugin, too.

Any idea how I can resolve this?

I really like this plugin, and yes, it’s very intuitive and thus simple to use.

Thanks.
