404 Error when submit

I get a 404 error just trying to visit your page.

This is most likely a permalink error in your WordPress setup.. you should check to make sure the permalinks are set up correctly and working properly. I doubt it has anything to do with your forms.

This is going to be a web server URL rewriting issue or an .htaccess configuration file issue.

The problem is the form action is being set to:

/index.php/fuel-levy.html

Instead of:

/fuel-levy.html

This is because the function used to get the URL is returning the index.php version due to either URL rewriting configuration or .htaccess rules.

I see you are hosted on a Windows IIS server. This is most likely the issue. While it appears rewriting is working, at the code level it is not. It's returning index.php/ at the front of every link. So this is a web server URL rewriting issue.

You will need to discuss this with your web host and I highly recommend avoiding the use of Windows IIS based hosting for WordPress sites.
