I've checked the phpinfo (v.7.4.30) and don't have a setting for max_form_fields but I do have max_input_vars which is set to 1000 and I think is the same thing? That should be OK though as there were 311 filtered results we were trying to update. Weird thing is that even if I only select two or three of that user's un-updated records they just won't update, but I added some test rows under a different user and was able to update them no problem. When would be a good time to call - remind me if you prefer Skype, Zoom or Teams?
