Hi @judyvedder,
thanks for your post, and sorry for the trouble.
I assume that you are referring to the Wordfence notification?
There isn’t really much to worry about, as you have already seen in the other forums thread.
TablePress 2.0 will contain an extra security enhancement regarding this. If you already want to use that, you can the current test version from https://tablepress.org/8-million-downloads-tablepress-2-0/ which is very stable already.
Regards,
Tobias
