How do I delete the logo that I added to my form?

We are sorry for this inconvenience.

I was able to replicate the aforementioned problem on your form and on the cloned version of it.  Even though the logo image is seen on form preview, the logo field does not appear on the builder to remove image or add a new one. So, I'm escalating this to our developers for a further investigations. 

On the other hand, you may want to try to inject following css code to your form as a temporary solution. 

.form-all:before {

  display: none !important;

}

This is the user guide shows you how to inject css code to your form: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes

Once the problem is fixed, you will be notified via this thread. We thank you for your understanding and cooperation.
