I saw the plugin was not tested yet for the newest wordpress but went ahead and gave it a try.
When trying to install though, you get a message (on a white wordpress page) asking if you really want to do this.
1st time I clicked yes and the plugin showed up in the plugin list but was nowhere to be found under 'settings'.
Going back to the plugins area, I suddenly dont see it listed there either. 2nd try I tried to install, same message came up but without an option to go ahead with the install.
It's a shame because I like the simplicity of the plugins of this developer, but so far every plugin I tried for the latest wordpress either didnt work properly or not at all.
