Lost pages, posts, images ….

My wordpress site is randomly losing access to posts, pages andimages. The nav/menu is also changing – losing pages.

They are pulling 404s front end, and in the admin area it’s like they never existed.

I can see all the images when I look at the site via FTP but the image library is nowlonger showing them.

I have tried a full database repair – this did not help. I tried to recover the database using an old export, this did not help.

I have woocommerce installed and that is losing images.

This is a very large membership site, and I simply cannot have dataloss like this.

Any clues anyone
