conflict with Insert-Page plugin

Hi,

thanks for a nice plugin that I have used for a long time and miss out on now.

I have found good use of another plugin named Insert Pages, but there seems to be a conflict. After trying for weeks to figure it out and searching for experiences I stopped using YARPP, but that is a shame and now I miss it.

Can anyone tell me what makes these two plugins conflict, and what I can do about it?

Here is an example of a post where YARPP works:

and here is one where it does not:

The ‘insert’ on the latter post that apparently conflicts with YARPP, is the gray bolded text towards the end of the post. See line
‘<div data-post-id=”3897″ class=”insert-page insert-page-3897 “>’

Thanks in advance for any input.

Best regards,
Henrik
