Contact form has been working fine, but now all of my forms have stopped and they give the message: Failed to send your message. Please try later or contact administrator by other way.
I have changed the "from address" to be one from my domain, and I have installed WP-MAIL-SMTP as suggested on various forums. I can send test messages via WP-MAIL-SMTP but I still get the error from the contact form.
I have contacted my website host and they inform me that nothing has changed on their side.
I am stumped!
You help will be most appreciated.
