• This plugin is not installing. Actually, it installs fine, but on activation, I get a blank screen with the message “The plugin does not have a valid header”. On someone else’s plugin, it appeared that it was due to WordPress 4.9 altering the way that plugins activate, requiring a small amendment to many larger, more complex plugins. I note that the WordPress site says that your plugin has not been tested for WordPress 4.9. I could probably look at the code myself, if I get time…
