How do I switch out of development mode in readiness to start inviting users?
Hi Cmackie, please go to the Admin panel. scroll down the page and click on "Production Mode" from the System Mode.
If you are referring to "Maintenance Mode", then follow the below mentioned steps:
1) Go to /admin/core/settings/general
2) click on Online option for "Maintenance Mode" field and save the settings.
Please let me know if you still have any concerns.
Please remember our Learning Center has all of this documented.
