Appereantly, it happend when using copy & paste to fill in the fields,we get the error mentioned above. Any idea how to solve that ? Copy Link Tim Geyssens 6167 posts 13896 karma points core May 06, 2015 @ 15:12 0 That's a strange error, so it happens on all copy paste actions of data into the form or only specific fields/values? Copy Link Ran Chen 28 posts 92 karma points May 06, 2015 @ 15:32 0 Strange it is. I've already removed the form so cannot get it now, will try to reproduce. thanks Copy Link Tim Geyssens 6167 posts 13896 karma points core May 06, 2015 @ 15:33 0 Ok thanks, just tried a couple of times but don't get the error Copy Link Isaack Rasmussen 14 posts 34 karma points Jul 20, 2015 @ 08:18 0 I get a lot of these errors but do not yet know what causes it. This is also with Forms 4.0.3 and Umbraco 7.2.5 Unfortunately, as we have discovered many forms that was never saved(=angry customers), we will be moving away from Forms.

I was following a guide to set up a contact form, using http://carlosmartinezt.com/2014/06/umbraco-7-and-mvc-contact-form/ as a reference.
