**Your software** My Mautic version is: 4.4.11 My PHP version is: 8.0.3 My Database type and version is: MySQL 8.0.3 **Your problem** My problem is: I am using Mautic in an Windows Server environment with IIS and Custom Objects. It works fine with the exception of issues with making a Filter on the Custom Objects Data for a date field using Date is Empty criteria. Tried installing Mautic 7 on a new Windows Server using IIS and Composer, I get to the first 2 steps of the configuration and then get the 500 Mautibot Internal Server Error. Was getting this error when I first tried installing version 5 years ago and settled on version 4. Is there any way of fixing this? These errors are showing in the log: Steps I have tried to fix the problem: ---

Somehow I got it to work. Next question, does Acquia Custom Objects work with Mautic 7 or is there a sort of replacement way of using Custom Objects?
