Hello,

This is a known issue related to tables that use server-side processing in wpDataTables.

In your case, you're using a Manual table, which always runs server-side processing when retrieving data (via admin-ajax.php calls).

You have two options depending on your setup:

1. Exclude the Page from Caching (Recommended)
Since this table type relies on server-side calls, caching can interfere with its ability to load properly.

• Go to your caching plugin settings

• Look for an option to exclude specific URLs

• Add the URL of the page where this table is located

• Save and clear your cache

This should resolve the issue in most cases.

2. Convert to an SQL-Based Table
If you prefer to keep caching enabled, you can rebuild the same table using an SQL query.

• Open the Manual table in the back-end and check the MySQL Table Name

• Create a new table using this SQL query:
  SELECT * FROM your_table_name

  • In the new table’s settings, disable server-side processing

• This setup will allow caching without breaking the table functionality.

  If the table loads fine for logged-in users (like Admins) but not for guests or on specific devices, it could be a firewall or security plugin issue.

  Here’s how to check:

  • Open your browser’s developer console (F12 in Chrome)

  • Look for red errors — especially 403 or 401 errors (forbidden/unauthorized)

  • Go to the Network > Preview tab to inspect the failed request
    (most likely an admin-ajax.php call being blocked)

  If you find a blocked request, it’s likely your hosting provider’s firewall is interfering. Please share the screenshot with your hosting support — they should be able to whitelist or unblock the request.

  Let us know how it goes, and we’ll be happy to advise further if needed.
