well I try to open OM in Moodle As soon as I got "Access denied" I tried one more time but this time with OM log side-by-side According to logs after successful hash checking, same hash has been checked 1 (or 2 or 3 times) Since the hash is one-time all subsequent checks result "Access Denied"
Since there were no issues in OM code And there were no other tabs I have checked browser developer console (Application -> Cookies) And there were no OM cookie I google it and find possible reason p.s. not sure if this description is clear enough, i'm not native english speaker :) On Fri, 18 Dec 2020 at 23:36, Daniel Baker <[email protected]> wrote: > Yes I have done that.
