I have several CF7 forms set up to contact different people and all appear to work fine. None have file attachment set up.
I recently set up a form (using the tag generator)to allow people to attach a file.
When I send a form with or without an attached file, the sending symbol - circling arrows - appears and the 'message sent' message does not appear.
However the email is sent - with the attachment if present.
Remove the file attachment tags and it works fine again.
Using the latest versions of WP & CF7.
I mainly use Firefox but getting similar effect in IE & Chrome.
Any ideas please?
