Date snap and safari home page trouble ... HELP!

I have added a datesnap stack with google calendar. here

It should show up under the Vitamin B Schedule button (or halfway down the page)

It did! Now it won’t show up in Safari ! Not only that but the three purple buttons that have been there at the top now won’t show up in safari either. They have become plain links jammed to the left!

Everything fine on Chrome and firefox.
Has my safari gone screwy? Help greatly appreciated as I need to fix before client sees it,
Same calendar is on the Vitamin B page and it works fine. Its just the home page is playing up. I have tried deleting other stacks one by one. But still no luck

It looks ok on Safari on my side


gosh thanks so much for that info.

How weird it is suddenly blocked on my safari.
