Dear Hikashop,

Can you please advise where I should be looking to fix the problem that is occuring since the upgrade.

I am not sure where to look to fix this.

Any help would be appreciated urgently.

Kind regards
Jennifer

Do you have calendar on your site?

Yes I do, but not on all pages.

It's because Google turned off Google Calendar API v2 several days ago.
Update the component/module you are using or disable it till it's updated.

Thanks for the advice, and taking the time to reply, I will try that.

Cheers
Jennifer
