Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly.

If you’re getting this error when starting phpMyAdmin, there are a few possibilities of what the problem may be.

For starters, be sure that it is a server side problem. If this only happens to one computer, just clear the browser cache and you’re good to go.

If that doesn’t solve the problem, it’s on the server.

PhpMyAdmin uses session intensely, check that the sessions folder of php is properly set.

Go to php.ini and look for the value session.save_path 

If there is a value for it, look for the path, it should be in mode 777 and owner root:user (change user with your own of course)

Sometimes this alone won’t solve the problem, check for you /tmp folder, if it is not 777, do it.

If this still does not solve the problem, clear the contents of the /tmp folder, some old session files stored in the /tmp folder do cause phpmyadmin to crash.

Since probably your /tmp folder is crowded, a simple rm -f /tmp/* might say “argument list too long”, in such case try this.

find /tmp -name '*' -print0 | xargs -0 -n 10 rm
