Hi PCN Web,

Can you please try to purge all cache from the site,

then refresh the page, let me know if this warning /notice is still the same?

-

Can you tell us is the WP_DEBUG enabled, in your wp-config.php on the server?

Sometimes PHP warnings/notices can happen like that,

let me know if it was enabled,  and if so,

if you can please disable the WP_DEBUG and see if it is the same?

-

Do you notice any functionality issue with any Table or Plugin settings?

And can you tell me what is the WordPress version installed in the Hosting server,

and what is the PHP version?

If we can also take a remote look at the WP-Admin,

please provide me a temporary WP-admin (administrator) user for your website where this happens, 

as well as FTP credentials 

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 parties. 

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

Hi PCN Web,

thank you for this, i am able to see the issue now on my local installation as well,

exactly as you said - if we go in the "updates" section from the back-end WP dashboard,

the error comes up right away.

I am not sure if this /same error comes up for all our add-ons including the main plugin wpDataTables,

it does seem so at the moment,

but i will certainly urgently send all the details to our developers and they will add a task to fix this as soon as possible.

Thank you for reporting it and for pointing us where to look.

 We don't have an exact ETA on when this fix will be added to the Plugin,

 but please keep a lookout on our wpDataTables changeLog.

It will be stated there during updates which bug fixes have been implemented at each update.

Thanks again.
