Hi,
After updating from Joomla 2.5 to Joomla 3.5 (and updating CF4) the form sender gets an error notification if there are attachments in the form. The notification with debugger is this:
Warning: array_values() expects parameter 1 to be array, null given in /home/leijonae/public_html/administrator/components/com_chronoforms/form_actions/email/email.php on line 205

Warning: Invalid argument supplied for foreach() in /home/leijonae/public_html/administrator/components/com_chronoforms/form_actions/email/email.php on line 206

Thank you for your help!

Hi Mediatonottu,

Max posted here that he had fixed that Warning so you might try upgrading to the latest release.

But as the Warnings are harmless you can also hide them by setting your Site Error Reporting to System Default or to None.

Thanks for your great help!
