Content was blocked on the widget

I just updated our website form at: https://guestsessions.com/contact.htm and see that the form now shows the short terms add in as being blocked because it was not signed by a valid security certificate.

However our website does have a valid security certificate and everything is fine without the add in.

Can you urgently advise how to get the form working as indeed it should.

There was a temporary issue with the widgets which was fixed shortly.

I have checked your website and the form is loading correctly.

We are sorry for the inconvenience.

I have to say that its still rather iffy now where the plug in seems very ropey in the design form...

I checked your website and it seems the issue has been resolved already,as what my colleague have stated.

Please let us know if you need further assistance.
