Why can't I post, view or download attachments in the customer forums? These forums are restricted to licensed customers only. Up to four forum user names can be associated with each customer account, enabling license owners to grant access for their site staff.
I have a license yet I still can't post, view or download attachments in the customer forums. Ensure you have associated your forum user name with your customer account. If you used the same email address for both accounts, they will be synchronised automatically; it can take up to 10 minutes to process.
