when using administrator account, i go to settings >>Technical >> security >> record rules i already given full access rights (R,W,C,D) to the Portal Personal Contacts with the ff domain filter of ([('message_follower_ids','in',[user.partner_id.id])] and the same with the res_partner res_partner: portal/public: read access on my commercial partner with domain filter of ([('id', 'child_of', user.commercial_partner_id.id)])

but still the same error, i actually try to give all access control list to my new account but same as the administrator, but still error.

Try deactivating them.

@ Mariusz Mizgier , deactivate the given access rights same as the admin? already did that and same error still.....

is this a bug? what do you think?

I would first try to look in the log for information, why this access denied error occured - you should have it stated if it is related to record rules or access record list - get this error, look up in the log and if you can't trace it, post the output here.

[Solved] I just uninstall the module and install it again. Whheeeewww.. btw thanks Mariusz!
