Thanks for reply Richard. I missed your message so sorry not to get back sooner.
As I don't use WMPL (I use Polylang) is there a way for the Ai1EC to appear on two different pages. In the plugin options it asks for the page for the Calendar to be placed on.
If pointed in the right direction I'll be ok with a bit of coding changes.
The reason I ask is that if I put it into one of my Welsh language pages then it translates ok but this means when I change to the English page (different page id) the page is blank (i.e. no calendar). I would expect this but if I can place two instances of the calendar on two different pages then I should get around the problem.
