Hi,
Thank you for using WCPT!
This error comes up if the plugin has not correctly loaded its overall settings during activation. To fix it go to wp admin > product tables > settings > click on ‘reset settings’. This reloads the overall settings of the plugin, but it doesn’t delete your product tables.
The above mentioned fix only needs to be applied one time and the error will not come up again. This error will be permanently fixed in the next version of the plugin.
I hope this information helps! For any other queries please feel free to write into [email protected]
Regards,
Kartik
