I don't know if this is helpful to anyone. But recently I started getting Permission error when someone submitted the form and it had an email field. I use the exported feature, as I have my own hosting.
What I found is this:
If I use the code that is provided by export to paste - it would have an error. But if I modify all the acsii code to < or >, then it works fine. Why this is I am not sure. I spent 2 days testing every possibility and the only way I can get any forms to work properly is by modifying the code. I posted an example below:
Paste Code from form builder: (note ascii codes for <>)
<script type="text/javascript">document.write(unescape("%3Ciframe id=\"fb_iframe\" src=\"FORMsponsor.php" + window.location.search + "\" width=\"600\" height=\"691\"allowtransparency=\"true\" scrolling=\"no\" frameborder=\"0\"%3E<a href=\"FORMsponsor.php\" title=\"FORMsponsor\">Check out my CoffeeCup Form</a>%3C/iframe%3E"));</script><noscript>
<iframe width="600" height="691" style="border:none; background:transparent; overflow:hidden;"
id="fb_iframe" src="FORMsponsor/FORMsponsor.html"> <a href="FORMsponsor.php" title="FORMsponsor">Check out my CoffeeCup Form</a> </iframe> </noscript>
I modify the same code to this and it works:
<script type="text/javascript">document.write(unescape("<iframe id=\"fb_iframe\" src=\"FORMsponsor.php" + window.location.search + "\" width=\"600\" height=\"691\"allowtransparency=\"true\" scrolling=\"no\" frameborder=\"0\">
<a href=\"FORMsponsor.php\" title=\"FORMsponsor\">Check out my CoffeeCup Form</a></iframe>"));</script><noscript>
<iframe width="600" height="691" style="border:none; background:transparent; overflow:hidden;"
id="fb_iframe" src="FORMsponsor/FORMsponsor.html"> <a href="FORMsponsor.php" title="FORMsponsor">Check out my CoffeeCup Form></a></iframe> </noscript>

This is just a FYI tip that worked for me. The permission error was random and usually triggered when someone with an aol.com email address filed in the form. Just quirky isn't it. Hope this helps.
Have a great day,
