Hi Guido,
Thank you for your reply. I’m sorry if my explanation was insufficient.
I am not having a problem with the captcha, but there are two issues.
Firstly, after sending the e-mail, if the page is refreshed, the message appears as if not sent and includes the old captcha number, although the original message was sent. Because the page was refreshed it requires a new captcha number, which triggers a red text captcha warning. The warning does not display properly and covers up a part of the field (see link to screenshot below).
The other issue that I have just discovered is that, if the consent box is not ticked, the e-mail is not sent and a red text warning appears, also not properly displayed: “Consent to having this web site collect my personal information via this form” (see screenshot link below). Perhaps this is intentional and the box must be checked to use the contact form.
The sending now seems to be working and the test email was received OK.
