Hi, Golden Nyirenda

Firstly, I would like to sincerely apologize for the delayed response as we have been experiencing an unusually high number of tickets. I am sorry that it has taken longer than usual to respond to your concern and your patience is highly appreciated.

-

Could you show me the SQL Query that was used for this table - and I can advise if maybe some small modification/correction is needed to get the filtering/search to work?

-

But you can also check these points to save time if you wish.

Our logic is based on a PHP SQL parser which has full support for the SQL dialect for the following statement types

SELECT, INSERT, UPDATE, DELETE, REPLACE, RENAME, SHOW, SET, DROP, CREATE INDEX, CREATE TABLE, EXPLAIN and DESCRIBE.

Some of them are disabled for security reasons.

Filtering, sorting, and search may not work properly if you include:

• Accent graves ( ` ) around the table name
• JOIN functions
• UNION functions
• CONCAT functions
• sub-queries

-

So, first you can check for accent graves around the table name, if you have this, remove it...

Then, see if you used CONCAT to create any column.

If so, go into this column setting, and disable it from "global search" in the Filtering tab.

-

-

If none of that helps,

you can try preparing a MySQL view (which will return the data that you need, call it e.g. “view1” and then build a wpDataTables based on a simple query like "SELECT * FROM view1″.

 If you need help with that, you can see our video, where we show an example of using View in our plugin.

-

Let me know If that helped, and i can take a look at the Query, as well.

-

If you can't solve the issue like this, 

It will be best if i can also check the back-end of the table setup for columns for you, if you want to save some time.

Please provide me a temporary WP-admin (administrator) user for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. 

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course, we do not provide login data to third parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.

And point me to the table ID, please.

Thank you
