Hi Dipesh,
Thank you for your purchase.

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.

Hi Dipesh,

I just deactivate/activate plugin and the error is not showing anymore. We suggest you should do that after every update.

Hi Dipesh,

The problem was in editor input type for date_modified column.
One-line edit was selected but we now changed to Date type.
If you have any date column you should select date type for editor input type if you want to edit dates.
Now your table is working without any errors.

Hi Dipesh,

You just needed to add Administrator in Editor roles. 
Please take a look at wpDataTables Support page where I created new table and edit it without errors. 

Hi Dipesh,

Sorry for misunderstanding.
I just changed the Editor roles because with Administrator role I can edit your table and see if that error pops up.
And I didn't see that error.

Plugin is working with Subscriber role and your subscribers can only read data. 
Do you want for your subscribers to be able to edit your tables or just to read them?

Hi Dipesh,

Can you please make and send me credentials for Subscriber user ?

Hi Dipesh

Your subscribers can add/edit and delete records from table.
I logged in successfully and now I see that error. 
You entered the wrong format for date (Attachment). Please change that and use date picker for dates.

Hi Dipesh,

You need to uncheck Visible checkbox to hide column that you want.

Hi Dipesh,

I updated the Status or Importance using inline edit for second row.
I could not update the first row because there is a still wrong date format ( Attachment). Please change that and use date picker for dates.
