Hi, George.

1. For filtering not working correctly,

we see this is an SQL Table.

- Please check this first :

For the MySQL engine, we are dynamically adding the accent grave ( ` ), so there's no need to use it around the table name in the query. If you were to delete them, searching and filtering should work just fine.

Let me know if you had the accent grave around table name - and if removing it fixed it?

2. If not, i will advise more about our SQL Parser ( when you have server-side processing enabled in table's Data source settings) :

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 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.

Thank you

2. As for showing advanced filters in a sidebar,

we have this option,

Advanced filter in a widget (in WordPress sidebar).

Please check more details how that works on this page.

Let us know how it goes. Thanks.

Hello George.

Sorry for the delay, but we can't access your website:

Can you please check if the URL is correct? If it is, can you white list access from Serbia and France?

Hello George.

It seems you removed the user:

I can now access the pages, but I see there are only shortcodes, which tells me you also deactivated wpDataTables. Can you please check the credentials, and I'll gladly check this out?
