During the night the whole website wasn’t available anymore. A simple explanation. My database had been erased.
Well. Today i had to build everything again, reinstall wordpress, import datas, cleaning things…. and i still have many things to clean but the main part is available.
I have lost many comments, lost all the “views” informations. But well. The website is back and alive. It reminds me “again” that regular backups are always useful :/
