I am using wordpress 3.3 with Headway 3.0.4 theme and I tried to use the contact form 7, which is a great plugin. BUT every time I try to save the contact form I get the following message:
Warning: in_array() expects parameter 2 to be array, string given in /home/digitals/public_html/limal.net/wp-content/themes/headway/library/api/api-write-panel.php on line 159
Warning: Cannot modify header information - headers already sent by (output started at /home/digitals/public_html/limal.net/wp-content/themes/headway/library/api/api-write-panel.php:159) in /home/digitals/public_html/limal.net/wp-includes/pluggable.php on line 866
Then when I go to the page, and test the form, everything seems to work normally, except that I cannot received the uploaded files in the received message and the message is never sent to the person who wrote the message.
Anybody can help? Note that I know nothing about PHP, so you have to be clear if the solution needs to use some og PHP code.
