Fatal Error – E_ERROR but site seems to be working ok

I went to edit a blank page today and got this error message.

As far as I can see, the site is working without issue but I’m about to launch my cart to hundreds of customers and hope this doesn’t cause issue with this.

I’ve never seen an error like this and hope it’s a quick fix.

Thanks in advance.
