Form has stopped working after moving from development URL to final URL

FAQ > After submitting the form, I get an error message stating “There was an error trying to send your message.” What is wrong?

Thanks!

Do you know how I could find out whether the issue is just due to the directory change, (for example I had to go in and manually reset a few thing in my Revolution slider after we switched to the permanent domain, so I thought maybe we were having a similar issue with the contact form) – however my client also switched up their hosting server right before launch; (I don’t know too much about servers/hosting so this is a little outside of my expertise, but what my client said was that the host recommended switching from a windows server to a linux server, so that’s what they did.

Any further help you can give would be greatly appreciated!
Thank you,
Lana
