ParticipantGreetings,
I have “AppSumo Tier 2 (all extensions, 10 sites LTD)“ since Apr 12, 2021.
I am looking to add Meta Box AIO to couple of my sites.
I don't see any option to add new domains.
Also, when trying to add my license in admin at:
https://mysite.com/wp-admin/admin.php?page=meta-box-updater,
it returns this error:
“Something wrong with the connection to metabox.io. Please try again later.
Please enter your license key to enable automatic updates for Meta Box extensions.
To get the license key, visit the My Account page on metabox.io website. If you have not purchased any extension yet, please get a new license here.“I tried the same process with all plugins at OFF and... still no success.
Wish you could fix this for me.

ModeratorHello Yves,
Thanks for reaching out.
I'm not sure what's wrong on the License page on your site, but you can use the workaround by adding the code below to the file wp-config.php to activate license key by code
https://docs.metabox.io/updates/#can-i-define-the-license-key-via-a-constant-in-wp-configphpdefine( 'META_BOX_KEY', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ123456' ); // Your Meta Box license key.Then you can try with UI option later.

ParticipantThank you Peter for your help. Much appreciated.
Clearing the transients and activating the key by the wp-config.php works perfect on both sites: A and B.
On site A, I can see the Extensions page while on Site B I can't.Site A:

Site B: Nothing
Site A: Meta Box Menu

Site B: Meta Box Menu

I am puzzled...
