Hi Aleksandar,

You can always send us any PHP warnings, notices, deprecated messages, etc., and our developers will work on removing them in future versions.

You can always double-check that you have the latest version on the ChangeLog Page.

( Currently, it should be 7.0.1 wpDataTables)

We are testing the Plugin for all these PHP Versions PHP 7.4 (7.4 is the minimum for our 6.0 wpDataTables) , 8.0, 8.1, 8.2, and I am personally testing PHP 8.3 -

We can confirm that there are no functionality issues, just some warnings like these and notices are possible to happen if you have WP DEBUG enabled.

For the production/live version of websites, the WP DEBUG should be disabled.

So please see if you can disable te WP_DEBUG on your Hosting server, if this is the live version of the Site, then refresh the Page? Then it should not show the warning anymore.

Our QA Team and the developers are trying to reproduce getting those warnings;

At the moment we are not able to reproduce this, we do see the warning coming up on your front-end Page, though;

Can you please send us screenshots or text of your 'System info' details, which can be found on our Plugin's back-end Page, then we will pass them to our Developer Team for further isolation and a fix in future versions if we can reproduce them.

And let me know if you notice any kind of a functionality issue with any table/or chart, etc.

Thank you.
