Multisite search not working anymore

Hi,

As you can see we use your ajax search on all our (sub) domains.

For an unknown reason it doesn’t work properly anymore. We enabled the multisite option from the beginnen and it worked. As of some time now it only shows posts from the head domain. Which is odd as all the selected sub domains are selected.

You already have access to our backend and ftp.

You can search topics like boventallig, ontslag or ziek. You should see posts from the same subdomain names

Please check whats missing or wrong as the search is in literly every post and page.
