Hi,
thanks for your post, and sorry for the trouble.
Indeed, the “TablePress Extension: Responsive Tables” plugin, which is an “add on” to TablePress, has been?retired?at the end of 2022. I will no longer update nor support it.
The reason is that its features have been integrated into the TablePress Pro and Max premium versions, that are now available on https://tablepress.org/premium/
Thus, the responsiveness features are now directly integrated there, without the need for a separate plugin, and with a nice user interface on a table’s “Edit” screen, instead of using error-prone Shortcode parameters.
(I’m not really sure why Wordfence lists this as “abandoned” though, as the plugin has never been part of the official www.remarpro.com plugin directory. And even though I won’t be updating or supporting it anymore (the Premium versions of TablePress that contain these features do however receive priority email support!), you can of course continue using it!)
I hope this helps ??
Regards,
Tobias
