Unable to start phpmyadmin

I installed xampp on my Macbook a day before. It worked perfectly yesterday. But today when I try to start the phpmyadmin it gives the following error:

Can't create/write to file '/var/folders/Uu/UuhwtR9xE3Ozsao8ttdIWU+++TI/-Tmp-/#sql1b5_8_0.MYI' (Errcode: 13)

Can anybody tell the solution for this problem?

Thanks,
Madhup

• Is MySQL working?

  madhup : Yups... its working

  mibus : That's particularly weird. I'm not familiar with XAMPP, but that looks like MySQL is trying to to table or index alterations into the given directory, and it either doesn't exist or it doesn't have correct permissions or available space. MySQL would be trying to put it in the same directory as the "real" tables, or in the nominated temporary directory. Check your config and filesystem layout?

• $ perror 13
  OS error code  13:  Permission denied
  

  MySQL is trying to create tmp tables and its now allowed to due to permissions

  Try adding the following to your my.cnf and restarting

  tmpdir = /tmp
