Hi Marc,
Thank you for your purchase.

Sorry for late response. 

We are located in Serbia and our working time is from 10:00 to 17:00 CET. business days.

Can you please tell me did you change something about wdt_ID column? That column is generated wpdatatables columns that is used for operations with data(editing,deleting and adding new data)

HI Marc,

Please provide me a temporary WP-admin login for your site where this happens, 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 party. You can write credentials here just check Private Reply so nobody can see them except us.

Also point me to the table id where you have this issue so we can investigate.

Hi Marc,

We notice that the generated column wdt_ID show up in modal when you try to add new data. That should not be possible. We made new table from that table and we call it Support and it's working just fine. You can check on website.
