Great plugin, but…

I’ve used this plugin for some time and it was the ideal solution for branding login pages. However it has come to my attention that the plugin now causes categories and tags to disappear from the dashboard (since update to WordPress 4.8). I have had to remove all instances of the plugin from my sites, because it is causing critical things to break. This is unfortunate, because it really is a great plugin. I hope that the developer is able to solve this problem.
