Hi,
thanks for your post, and sorry for the trouble.
I’m not sure what happened there, but resetting the TablePress access capabilities should do the trick.
To do that, go to https://your-site.com/wp-admin/options.php in the browser. You should then see the list of “WordPress Options” with input fields to change them. (This is a powerful screen in WordPress, so be careful.)
Scroll down to the “tablepress_plugin_options” option. In that text field (be very careful), change the number after “plugin_options_db_version” to a 0 (it should be 34 right now, I think). Then save the changes.
That will reset some stuff inside TablePress internally and should also re-add the capabilities, so that you can then see the TablePress entry in the admin menu.
Regards,
Tobias
