Internal pages vanished…please help

Hi All,

I hope someone can help because I nearly lost a client yesterday through this issue. I haven’t altered my site for a while but this person brought to my attention the fact that most of my internal pages have vanished.

They have been replaced with a grey page that has a single, diagonal line passing through it…like this:

https://www.nickstubbs.com/wedding-photographer-dorset/

When I go to edit the page, all the info is there with no apparent problems. Also, when I try to build a new page and “preview” it, I get the same grey page with line.

Any help or suggestions would be gratefully received.

Many thanks,

Nick
