Hackers and SQL-injection protection.
Hello guys,
To enhance the security of my Wordpress- classipress site I've changed the table-prefix wp_ of my database into a abcd_ and I've changed the same wp_ prefix in
wp-config.php, but when refreshing the site it's throwing the next error on the frontpage / home-page:
Warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object in /home/xxxx/public_html/xxxxxxx/
wp-includes/widgets.php on line 858
Am I doing something wrong?
How do I enhance the security of the site against SQL-injection by hackers?
