Does not allow saving post second time

I was able to setup the plugin nicely, however after testing, it is clearly buggy.

For example, if a logged in user saves a posts and later removes it, then again wants to add the same post to favorites, the plugin does not record the second time saved. What is happening, when the post is deleted from the database, the post is not actually deleted, it only appears to be deleted. When a user tries saving again, it fails to save because the previously saved post is still in the database.

So yeah, time to move on to the plugin “Favorites” which has support.
