Can you check https://openelms.e-learningwmb.co.uk/jackdaw/login and log in as admin_jackdaw and try the Pro and Free roles.
I get a permissions error on trying to create a site.
I think this has been like this since mid feb at the least.
Can you sort please and let me know if we need to do anything on other sites too. Not sure why this is the case as it was working when first set up.
