I’ve been trying to figure this out myself, but have come up with naught other than I believe it to be some kind of security issue.
We have an application that uses a number of nested forms, and on the child entries, the parent ID # ends up as 0 (zero). The field entry record on the parent for the nested form field is also missing. Everything works fine if I do this as an admin, but fails for the general public (no login). I have not yet tried a person with a login without admin rights.
I put in a ticket to support last Friday, but have not heard back. In trying to solve this, I’ve looked out on the net, and some problems have come close, but none clarify exactly what they did to identify the problem nor the exact steps they took to solve it.
I enabled logging on Gravity Forms, and I don’t see anything obvious in the GF Core log, but the nested log file shows entries like this:
2025-05-14 18:55:20.053095 - ERROR → GPNF_Session::get_session_path(): No path found in AJAX request. Request details: %s
The form does have a AJAX error when saved in design mode, but I’m not sure if it is related or not, or if that’s indicative of a problem with AJAX on the server in general (this site is hosted on WP Engine). I can ignore the error and the form does save correctly. Also as noted, everything works when I try it as an admin.
What I’m looking for is some general direction on troubleshooting (I am not a web developer). i.e. is there verbose logging, what do I look for, when do those Parent ID’s get
assigned, is there a temp directory that is used for the operation, etc.
I have tried turning off caching, but have not run through a plugin conflict check yet. Was hoping to at least get an idea of what to be looking for before I dove into that.
While not a web developer (normally desktop), and Word Press/PHP is entirely new to me, I am getting the feel of all this, but need some help to get pointed in the right direction.
