Wordpress is not posting content

While writing a new post I noticed that I could not change from visual to code so I continued to try.
Once I gave up and posted a new post without links the content disappeared (on my website and in wordpress controls).
And when I go and attempt to delete these posts that have no content they will appear deleted but then come back up once I refresh.
does no-one know what is going on?
