I am an admin for www.biokineticshealthsystem.com , and now I cannot read the Matomo reports anymore.
When trying to click on REPORTING, the message reads:
You don't have permission to access this resource.
Thanks for letting me know what to do from here!
Maybe there is also already this question solved there, eg https://forum.matomo.org/t/403-forbidden-error-general-query/33359/2. I will close this for now.
