I have a simple entry form on the frontend that will not save form data. After submit it returns to the form page with no errors, rather than going to the url I set in the redirect variable.
I have done this dozens of times on other sites - the section ID is correct, the user has permission to create an entry (even tried as SuperAdmin, same failure). I then tried using the sample form from the Craft docs page, still no luck. I even recreated everything verbatim on another Craft site and it works fine.
Server configuration seems fine and there are no other issues with the website.
I am pulling out what is left of my hair trying to figure out what is going on - any suggestions would be greatly appreciated!
