phpMyAdmin: Method Not Implemented, GET to tbl_change.php not supported

I suddenly got this error when trying to edit a table record using phpMyAdmin.

To fix this, add this to your /etc/httpd/conf/httpd.conf, inside the block that starts with <Directory "/var/www/html"> (the path of the root of your Apache directory tree):

SecRuleEngine off

Alternatively, you can write a separate entry only for the directory where you have installed your phpMyAdmin (/var/www/html/phpadmin in my case, but probably different for you):

<Directory "/var/www/html/phpadmin"> SecRuleEngine off </Directory>

Then restart Apache (/etc/init.d/httpd restart) and all should be ok.
