Impossible to attach files

Hi,

I’m having a big problem “error, please contact your webamster…” when i try to send a form containing files, regardless of the format or file size.

For the moment, we have 3 problems who needs fix :
– SSL secure : Javascript is not included in the SSL protocol
– File attachment : Impossible to send files with a normal e-mail
– Extract from the dev console : “The page at ‘https://domain.com/contact/’ was loaded over HTTPS, but displayed insecure content from ‘http://domain.com/wp-content/plugins/contact-form-7/images/ajax-loader.gif’: this content should also be loaded over HTTPS.”
