Divi them Pages showing but defaulting to Post when trying to edit

I recently made a site using Divi theme and the Divi builder.

It has been functioning well. I changed hosting companies – had to do a full C-panel back up – since doing this I cannot edit the Pages I have created.

I can see them, open them – but when I edit and publish them it shows Post item – not the Page and nothing is edited … it is doing this for all of the Pages. There are no single post pages on this site?

Any idea what is happening here?
