I have been using form builder on my websites for a while, however this is the first time I've included the option to upload a file on the form.
The new form I created with the upload option works perfectly when a file isn't uploaded with it (all emails are sent to both parties and form info is received via email).
However, when a file is uploaded with the form, the email notifications are not being sent to the submitor or the submitee.
After submitting the form, it does lead to the "Your form was successfully submitted" page and the form submission info and uploaded file are correctly saved in the database so that still works fine. The emails just aren't being sent/received when a file is uploaded with the form.
I have checked the spam folders and completed all of the details in the Form Settings > Email section, with the Reply-To option to an email that exists on the same domain as my WordPress site.
PHP is version 5.3
MySQL is version 5.0
WordPress version 3.5.1
wp-content permissions are set to 755
I have also optimized my server settings in the php.ini file as suggested here: http://vfb.matthewmuro.com/faq/recommended-server-settings/
My server host is Startlogic.com. I contacted them and they said that it was an issue that they couldn't solve on their end and to contact the plugin creator for support.
Thank you for your time & consideration!
