Hi @rywn
No worries. Just let them know of the thread here and that there is a conflict between relevanssi and ACF PRO on the relaitonship field which uses get_posts during an AJAX request.
Also let them know of the PHP errors you attached above as these point to code within the relevanssi plugin.
I’m not sure why the issue is occuring, but hopefully they can point us in the right direction
Cheers
E
