Crashed my site on install

Hi Herymamy, It would be helpful if you could say what you mean by crashed. Did you get any error messages? If yes what they were? Very often the clue what is wrong is in the error message itself and often removing new version and installing back the previous version sorts out the problem. I am sure that the developers will sort out some problems new version is causing on sites but before you do anything please do what I did with my website as right now I am happy.
