Hi Gloria, 

my apologies, but i am not able to determine what the issue seems to be just from looking at this error message you sent.

I am also not able to see anything on your related URL, it requires a logged user :

Can you tell me more details about this issue, please?

1. What is this table type?

2. If it is a table linked to live source data, did you change the data structure on the source such as :

• Changing the column’s name,
• Changing the column’s order,
• Deleting the column, and
• Adding a new column.

If you did this to a table linked with a source file,

it is highly not recommended, because the table in the wpDataTable plugin will not work, at the moment. 

If you make any of these changes, please recreate the table again.

3. I can still send this error for our developers to see if they can draw a conclusion just from the error text;

but if you can please provide some additional details;

if it's possible to add any screenshots or a Video showing which steps you did when this happens and how it looks;

is it only on front-end or also at the back-end of the table, etc?

If you need to show any sensitive data, please mark the reply as PRIVATE.

Thank you.
