Hello Александр

Please note that English is the only supported language, so please translate your future questions.

If I understood you correctly, you cannot open this table even though it exists? There could be many different issues causing this, so I would need to take a look.

Please provide me a temporary WP-admin login 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 party. 

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

Glad to hear it's working now, Александр

If you have any further questions or issues, please feel free to open a new ticket, and we'll gladly help.

Hi again Александр

We are not familiar with that plugin, so could you please send us the zip installation of that plugin, and we'll see what we can do about it?

You can email it to me: [email protected] or you can add it to your response, just make sure to enable the PRIVATE response.

Hi again Александр

These errors that you see are usually caused by some security plugins blocking wpDataTables admin-ajax calls. When the table loads or does some filtering, sorting, search, etc, an admin-ajax call is sent. If something blocks that call, the JSON response the plugin is expecting to receive returns broken.

I can't find any tables on your website, so can you please tell me on which page I can see these errors?

Alright, Александр

I responded to your email, so we will see what's going on when you inspect the page.
