I've been playing with the membership and groups of the https://friendsofstgeorgepark.org.uk/ site of which I am (or was!) an administrator and now cannot access the admin & edit functions. I can access the site as a basic member.
The group has only one other member, a test member who is not an admin.
Can anyone help, please :(
Not sure how you did that - but yes somehow you managed to remove Admin rights from youself. This isn't supposed to be possible!
Anyway, I've now restored admin rights to your Nick B account, so you should be able to edit your site as before.
