Warning: Invalid argument supplied for foreach()

Hey, I started working with Emailforum and build in my first Newsletter.
Mostly everything is working except that right under the newsletter is written that there must be a error.

Warning: Invalid argument supplied for foreach() in /var/www/web24838789/html/root/fave/wp-content/plugins/tco-email-forms/email-integration/views/site/shortcode-x-subscribe.php on line 190

That is what is written there right on my website, but I don’t know how to fix it, hopefully some of you guys can give me some help.
Take a look at that issue right on the website: http://fa-ve.de/gutschein/

Thanks in advance.

Hi there,

I am not sure exactly, but as I know it is an old bug which is fixed already. Kindly make sure that you have the latest version of the Emai Forms plugin.

For further investigation, we will need the URL/User/Pass of your website given to us using the Secure Note feature of the post.

Thank you.

Thanks for your quick respond.

Hi There,

Thank you for the credentials. I can see you have updated Cornerstone but X theme is still version 5.0. Please update X theme too. See latest version here: https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195

I updated the Version but unfortunately it is still not working as it is supposed to be rather the error is still written there.
Hope you guys can help me.

Hi,

In that case, kindly provide us your ftp login in Secure Note.

Thanks

Sure, thanks in advance
