That is strange. This plugin shouldn’t remove what is sent to the server. Does it work for a single form without the multistep tag?
It seems like the URL you pasted doesn’t exist anymore. If you could post the url to the form it would help me to determine what might be wrong.
I have made the link available again for you to check. The Single form is working fine but the photos I am attaching in the single form are not received on email.
I can’t see anything wrong with the forms on the link you provided. What exactly are you seeing in the email you get?
Make sure your tags on the Mail tab just have the field name. For example [your-email].
You can also see an example on the last step of the example form. Below the form click on “Click to view relevant code on the Mail tab”.
