I went onto my website and found that the menu bar along the top was completely different to what it should be. It had the normal home button, but then the rest of the pages apart from 2 were subpages (not parent pages) which are now displayed as parent pages.
I logged onto WordPress and onto the Pages section and I couldn't find the missing pages anywhere, not even in the trash.
The only editing I done that day was to remove subscribers and unticked the box about allowing anyone to register, it had been fine before the weekend (I hadn't checked it until yesterday).
I am not sure if this is a glitch or something with WordPress, something I have done (I can't think what) or a possible hack. Any advice would be greatly appreciated!
Thank you in advance.
