I have a problem with file attachment. When the file size is too large (more than 10mb) the warning message doesn't show. But when the file is less than 10mb all works fine.
I try with the default theme, deactive all plugins and without others scripts. Also I used Contact Form DB and Contact Form 7 - Dynamic Text Extension, but i try without this plugins and nothing work for me.
The link of the form is:
And my code for the attachment is [file* adjunto filetypes:zip|rar limit:10mb]
