I have a curious problem with a website I have inherited to run.
It appears that a WordPress update has removed the Subscribe2 plugin and the form has vanished from the subscribe page.
I know that Subscribe2 used to work on the site as people are still getting new post notifications.
I am hesitant to re-install Subscribe2 in case this interferes with the existing database - but I need to get control of the existing database as people cannot unsubscribe.
If anyone has experience with this situation I would very much appreciate any suggestions or advice.
