HI trendtype,
Thank you for your purchase.

Can you please tell me do you have installed mod_security on your server because this error when the date appears is almost 99% related to mod_security.

Best regards.

Hi trendtype

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

Hi trendtype,

Can you please provide me temporary WP admin credentials because I can not login with the old ones.

Just please check PRIVATE reply so nobody can see it except us.

Best regards.

Hi Francisco,

Maybe the best option would be to ask your hosting providers to disable the mod_security for you rather then changing the files by your self.

About the downloadable charts: We are using third party libraries for displaying the chart and unfortunately only highcharts library have the option to download their charts.
Something like this is not on our side.

Best regards.

HI Francisco,

Can you please tell me are there any server errors in the server log after you see this date.

Best regards.

HI Francisco,

This is the message that I get when I now try to configure the table ( attachment) 

Also can you please deactivate WordFence plugin and tell me do you still have the same issue.

Best regards.

Hi Francisco,

The issue with the WordFence plugin is that they have some security that is not allowing editing and configuring our tables, or any communication with the database where that tables are saved.

So now when we know the issue is because of it, my suggestion is to ask Word fence team to whitelist our plugin if that is possible on their side so you can use both plugins at the same time.

Best regards.

HI Francisco

The pleasure is mine, hope that everything will work fine.

Best regards.
