on my wordpress 3.3.1 website - http://phillybhatesme.com, i use contact form 7 for my us contact page and my international contact page.
the form works 90% of the time or so, but once a day, i get reports that people filling out the form get the "# Sender's message was failed to send" message.
to fix this issue, i go to my dashboard > contact form > click "save" for both of the forms > go to the pages section > and update both forms.
no clue why this "fixes" my issue, but i'd like to be able to keep the forms up and running without having to "fix" this issue each day.
any ideas on how to help fix this issue permanently?
