PhpMyAdmin出现export.php Missing parameter: what /export_type错误解决方法

phpmyadmin 不能导出数据的问题，点击导出后先是一个请求失败或者白页，重新刷新后就报错
export.php: missing parameter: what (faq 2.8)
export.php: missing parameter: export_type (faq 2.8)

解决方法是：

php目录下的php.ini 设置要调整一下
原来的 post_max_size = 8m ，改大到 post_max_size = 20m 就好了。

php源码中解决办法

ini_set('memory_limit', '180m');

如果在linux系统中我们就

change directories into the folder with the affected file. cd

/usr/local/psa/admin/htdocs/domains/databases/phpmyadmin/librariesmove

the old file as a backup. mv session.inc.php session.inc.php-olddownload the fixed file. wget
