PROBLEM

I installed the simple email form on a clients website. It is a Joomla 3 website on PHP 5.3 using the form is on this page:  http://some.company.com/

On submit I receive the following message:
Warning: strip_tags() expects parameter 1 to be string, array given in /home/users/some/company.com/modules/mod_simpleemailform/helper.php on line ...
I get the feeling I am overlooking something simple...   Can you help?
 
Best regards, Marco
 

SOLUTION

Found out what caused the issue few minutes ago... forgot to add a subject field. Now it works, Thanks anyway!!
 

DISCUSSION

The "Subject" field is required.  In future releases I will add an internal check to make sure that a default value is supplied if none is given.
Thanks to Marco for finding this problem!
