Error Loading DataTables

Hey there,

First, just a quick note — I see you’re using the Premium version of wpDataTables. This forum is dedicated only to Lite support, so for any Premium-related issues, please open a ticket using the steps in this guide:
https://help.wpdatatables.com/en/articles/39-how-to-contact-support-with-your-premium-license

That said, here’s what’s causing your current issue:

If the table was built using Premium features — such as a Manual table, SQL Query-based table, Google Sheets, or any of our add-ons like Master-Detail or Powerful Filters — it won’t load properly with the Lite version.

Here’s how to resolve it:

1. Reinstall the Premium version of wpDataTables.
   You won’t lose any data — just follow the steps in this guide:

2. If your table uses any add-ons, make sure they are also installed, activated, and compatible with your current wpDataTables version.
