I upgraded from 14.4.4 today, to version 15, as I was anxious to use some of the new features.

I have a 'Contact Us' form, which I have been using successfully for some time, with previous verisons. I opened the last file in version 15, and saved it, without making any changes. I published only the Contact Us page in it's original configuration, and the form web page displays and works as before. So far, so good.

Next, I opened the form properties, selected Advanced, and then Miscellaneous. I placed a tick in "Do not allow URLs in form data", and closed the properties as usual. After I publish this page only (contact.php) I see only a blank web page. I've tried viewing this page in Chrome, and Firefox. After I 'untick' this option (Do not allow URLs) and re-publish, the web page works again.

I must be doing something wrong, but don't know what...

Thoughts?

You are right, there was an issue with this option.
It should now be fixed in the latest build (6/29/2019)

I installed the latest build, and YES, no problems, no errors !!

I had been getting occasional spam with URL links to questionable sites, so I am hoping these type of human-caused headaches will be alleviated.

Thanks for all your work !!
