I am trying to Insert a new form. When I am trying to select a placeholder for the form, following error is showing :

when I had installed the WFFM, I went to "Restrict placeholder" and added my placeholder, like below enter image description here

I googled the issue, but coudn't find any relevant solution to this.

So I got why this error is coming. I installed WFFM first in my sitecore instance, and then I installed SXA. DUring SXA installation, a popup came :

and I chose "Side by Side" option and clicked "Apply to all". After installation, when In add form, it show the error during selection of placeholder. If I choose Overwrite option, SXA will not install.

Any suggestion what to do?

  • Did you try to check if you have written some cookie modification code or you have extended a pipeline? Because as per the links below it may be that your pipeline is executing & trying to modify the cookie but it does that before it the request for the form already sent the headers back to the client & you get this error.

  • Also, check if you have somewhere the URL redirecting code, and you are trying to set the cookie after it then you also get this error. – Prashant Tomar Dec 7 '19 at 8:37
  • Which version of Sitecore and SXA? – Mark Cassidy Dec 7 '19 at 14:32
  • Sitecore 8.2 update 1 and SXA 1.2 – Kautilya Dec 9 '19 at 2:16
