Hi Steven,
it was never an issue activating or deactivating the plugin from wp admin, it was when the plugin is deactivated it takes the site down and it appears it has been down since you deactivated the plugin.
I have logged in to wp again and reactivated the plugin.
can you please have another look and ensure the front end https://www… is also still online. make sure you’re not seeing a cached copy…
Thanks heaps for your help Steven, I know we’ll get to the bottom of this.
