Cannot reinitialise DataTable
-
I’m having trouble with an error message with a fishing tournament roster. The error does not occur until the table is completely loaded.
DataTables warning: table id=table_1 – Cannot reinitialise DataTable. For more information about this error, please see http://datatables.net/tn/3
I was working with Allan on another related forum to resolve this. He did determine there’s a javascript file that is initializing the table. Further, he informed me that:
“The other, as you indicate will be in wpDataTables. If you are using wpDataTables, you don’t need to initialise a DataTable yourself. Use its configuration options in its UI to control the features of the DataTable.”
He was not able to help me further, so I’d like to ask for some insight in correcting this error so that it does not happen moving forward.
I found several code snippets concerning this error, and input them in the “settings” code section of wpDatatables – but the error persists.
Thanks for any assistance!

Hello,
Can you first confirm whether you’re using the free/Lite version of wpDataTables or the premium version?
Regarding the issue:
Please check if the table loads correctly on the back-end.
If it does, that means the issue is specific to the front-end, where something else on your site is preventing our table from loading properly.Can you also confirm whether there are any other DataTables elements, content, or scripts on the same page as your wpDataTable?
Even though wpDataTables is built on the DataTables jQuery library, they can’t be used together on the same page. If another DataTables script tries to initialize a table, it will conflict with ours.If you’ve added any custom JavaScript or CSS snippets in Settings → Custom JS & CSS, or through your theme/page builder, please remove or temporarily disable them and test again.
The best way to confirm if the issue is caused by a theme or plugin conflict is to create a new blank page with only the wpDataTables shortcode and see if the table loads.
If it still doesn’t load, please try the following:wpDataTables works on a WYSIWYG (What You See Is What You Get) principle — meaning the table or chart should look and behave the same both in the back-end preview and on the front-end.
If it looks or behaves differently on the front-end (e.g., missing features, broken filters, or console errors), that typically indicates interference from another plugin, your theme, or a page builder.Here’s what to do next:
- Switch to a default WordPress theme (like Twenty Twenty-Four) and test again.
- If the issue persists, deactivate all other plugins except wpDataTables and reload the page.
- If the table now works correctly, reactivate your plugins one by one, refreshing after each activation, until the issue reappears.
This process will help you identify what’s causing the conflict.
Please let us know if you need further assistance.
Kind regards,
MilosHey there,
Thanks for the update and for testing with a blank page to confirm that both the back-end and front-end load correctly otherwise.
Since the “Cannot reinitialise DataTable” warning still appears even on a clean page, it indicates that something on the site is still trying to initialize the same table a second time. This can sometimes happen if a theme or page builder script automatically targets all HTML tables on the page and applies the DataTables jQuery library to them again.
Once you have a chance to test by temporarily switching to a default WordPress theme (like Twenty Twenty-Four) and deactivating other plugins, that should help confirm whether this is the case.
If the issue disappears after those tests, please note which plugin or theme seems to trigger it so we can document it and check if we can advise on a possible workaround or solution from our end.
Kind regards,
Milos
