Not Acceptable!

Hi Hugh,

In regards to a site on your hosting account, the cause of the 406 error is usually due to a mod_security rule on the server. Mod_security is a security module in the Apache web server that is enabled by default on all hosting accounts. Apache web server, scans for violations of the rules it has set. If an action occurs that violates one of these rules, the server will throw a 406 error.

1. If you’re receiving this message when trying to save wpDataTable based on MySQL query from your WP Admin, it means your hosting provider is restricting access to some of WordPress’ native functionality. To solve it, contact your hosting provider to ask them to remove this restriction.

2. Adding the following to the top of your .htaccess file. (This should be a temporary measure. You could try it just to see if it will work, but you probably don’t want to leave it.)

<IfModule mod_security.c>
SecFilterEngine OffSec
FilterScanPOST Off
</IfModule>

3. Backup your .htaccess file if you have one in the public_html directory.

Open the .htaccess file with any text editor and observe the lines between the “# BEGIN WordPress” and “# END WordPress” tags. Make sure the lines look somewhat like the following. If not then update the file with the following content and upload it to the ‘public_html’ directory.

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
