Hi,

Somewhat distressingly our "Subscribe" button has stopped working. I have disabled plugins/modules installed since the date of the last successful subscribe and this does not resolve the issue so I am at a complete loss and it is affecting our credibility on the site ( www.greenjourney.com.au )

I have perused the site and whilst it seems lots have had this problem, it has been for all sorts of reasons.

Can anyone suggest what could be wrong if it does not appear to be any modules or plugins which have been installed.

Thank you very much.

Looking at the chrome console (by pressing F12 and reloading the page) it seems that the line breaks in your messages are the reason. Try replacing them with \n or <br />

Thank you very much for taking the time to assist PaulyD.

It seems you are 100% correct.
