IMPORTANT: do NOT delete ibdata1 file. You could destroy all your databases. Instead, first try using the MySQL backup folder which is included with XAMPP. So do next steps: 0- Cierra Xampp 1- Rename folder C:/xampp/mysql/data to mysql/data_old (lo puedes borrar al final si funciona bien) 2- Make a copy of mysql/backup folder and name it as mysql/data (esto realmentees lo que recupera el sitio) (haz 3 y 4 si realmente quieres recuperar tus tablas danadas, si no saltate al 5) 3- Copy all your database folders from mysql/data_old into mysql/data (except mysql, performance_schema, and phpmyadmin folders) 4- Copy mysql/data_old/ibdata1 file into mysql/data folder 5- Start MySQL from XAMPP control panel
