I have created a page with an html form on it. Using Form Tool Kit 1.0 I have inserted a captcha and applied server validation to the captcha and a few of the other fields. I then used UE4 to have the form emailed to me. I uploaded the page and all dependent files to my server and when I view it in a browser the page is blank, the error message I get from the browser is "internal server error". However, the page shows up fine if I delete the php scripts WA installs. In other words the html page and form seem to be OK.
I have tried but can not find the problem. I do appreciate some help on this.
I have attached a zip file of the page.
