When I select the option to attach a form, no matter what kind of attachment I select, I get a "File format is not valid" error. I get this error with docx, doc, pdf, mpg, and any other extension I have tried.
I have re-downloaded and re-installed the contact contact manager with the same results.
I have the same problem with a Vista and Windows 7 operating system on two different computers.
With no attachment selected the form works as advertised.
I am using the current 3.5.1 version of WordPress.
The URL of the page where I get this error is:
Can you help me please?
