That’s normal operation. 🙂
This plugin will do what you want: https://wordpress.org/plugins/remove-dashboard-access-for-non-admins/
Thanks for that but and have since fixed with Peter’s Login Redirect.
The weird thing is our site has been sending users back to home page since I build site 4/5yrs ago. I’ve recently binned our forums (no body used them) so can only assume that I’ve also binned whatever I did in the first place to redirect to home page. Sort of “baby out with the bathwater”. Binned about seven associated plugins along with bbPress so that was probably what caused the problem.
Thanks for you help anyway,
Cheers and stay safe,
