WordPress Auto-Trashing my Page

Hi I hope someone can help.

For some reason one of the pages (page not a post) on our site keep automatically putting itself into Trash.

I can’t seem to find anything through searching the web about anyone else having this sort of problem. Many search result talk about the auto-deletion of posts/pages already in the trash, but nothing about pages mysteriously Trashing themselves???

If any one has any ideas on what could be going I would love to know, we temporarily fix it each time by re-publishing so not a massive problem but would love to know if there is a reason it does this.

Doesn’t seem to have any pattern to when it’s trashed (e.g doesn’t happen for example every Sunday or at a given time) , just seems to be random.

The page has no physical content as it is using a page template to pull in the information.

Any information would be great, I’m not the developer of the site, more an administrator. I have a fairly good understanding of WP but this one is just baffling me!

Cheers

Martin
