If you see this message in your phpMyAdmin
“Cannot start session without errors, please check errors given in your PHP and/orwebserver log file and configure your PHP installation properly”.
The following solution may help.
Go to your phpinfo, take a look of the temp path and see if the folder really exists.
Check this field
If not, create one folder or you can modify the path.
If this doesn’t help, then, sorry, go to google.com again and seek for another solution.
