While accessing phpMyAdmin the following error was popping up
Error during session start; please check your PHP and/or webserver log file and configure your PHP installation properly. Also ensure that cookies are enabled in your browser.
session_start(): open(SESSION_FILE, O_RDWR) failed: No such file or directory (2)
session_start(): Failed to read session data: files (path: )
Fix:
Make sure that tmp folder under the user home directory contains necessary files.
If it is corrupted, copy from available backups and try loading phpMyAdmin.
