Wordpress install again?

I can create my website, edit it the way I want, however, after 2 posts it appears to install Wordpress again and this frustrates me a lot because I’ve lost 3 sites because of it. When I put my username and password again it is in infinite looping. After that I can’t access my WordPress anymore0123

And how long do I have to wait for my site to get back to normal?

If you read the above thread there is no specific time period.
