I’ve just purchased a CV SSL Certificate to resolve this problem with Microsoft Edge – will give you an update on this!
Thank you for your reply. Smooth Themes support team have corrected this now.
I’m having issues with the ‘register’ or ‘enquire now’ buttons – none of them send me the message from the person entering an enquiry or booking an event. They also don’t received confirmation that their message was sent. Also issues with the front page slider overlapping the elements below it – which never happened before upgrading WordPress and adding SSL to my site.
