No longer works afaict

I couldn’t tell you which version but after one of the latest updates to WordPress, the plugin no longer works for me.

It was bound to happen. Email warnings have been issued by WordPress for some time. It hasn’t been tested for the last three major releases of WordPress.

Looks as though the plugin development and support has been completely abandoned from looking at the support tickets.

I have a simple site using this plugin so it’s not likely to be an issue of a conflict with another plugin. Still could be something on my end but … my take: find another avenue to explore. This is not the plugin you are looking for.
