Unable to Create Donate Button (HTTPS not recognized)

[PastorBuddy]

I am not able to create a Donate button with optional Logo.  I receive an error message :  Invalid URL. The URL needs to be HTTPS for security.  The image below shows the button creation screen with the HTTPS site and URL and the logo is displayed.  I am not able to continue with creating the button because of the error message which does not make sense to me.

The logo image has to be hosted on a secure image host. Upload the logo to a secure image host site like Flickr, postimage, Imgur, etc. and use their https image url. Or try adding "www." after "http://"

The image is on a secure site (https) - see the URL which is in the image included with this post.
The problem seems to be that spaces (html %20) are not allowed in the URL.  I was able to create a button with an image that does not included spaces in the name.
However, the logo image does not appear in the code that is generated.

Thanks for your reply.  I will likely use some kind of work around by creating a custom button and using "Shareable URL" code which is generated.
