Updated to version 3.8 and Admin pages are very slow. How to diagnose problem? [closed]

Tried all these:

  • Default theme
  • Renamed plugins folder
  • Deleted .htaccess
  • Restarted server

Nothing worked but finally this command made it work:

mysqlcheck -u db-username -p db-name –repair –databases

Hata!: SQLSTATE[HY000] [1045] Access denied for user 'divattrend_liink'@'localhost' (using password: YES)
