Hi I am trying to work with easyforms and while I tried to configure the mailer I got this error and here the is traceback

What I found from this error is that, there is something wrong with the templates but I am not able to figure out which tempate as I am finding the base templates seems okay when I checked them, it may be an error when we are passing the mail body and mail header to the templates through python code, may be there is come error I am trying to detecting it but till now can't figure it out, so it will be great I can know that I am going in right direction for this error. Any other inputs will be great too.

Thanks.

So Finally it worked for me as the error was in the template that has been provided in the template option of the Mailer and I just tried the template of PFG for easyform and it worked perfectly for me. It was a silly mistake but though it took few days to detect it. Now its working perfectly for me.

Cheers,

@jensens I guess we can close it. I have created a separate branch for correcting the default template on collective.easyform
