Hi @bondtheangelwings-net,
Thank you for your purchase.
the subscriber can’t attach the file, only admin. The subscriber can’t see the button no matter how many ways I have tried.
The attach file button is only available for Usergroups who have “Can attach file” permissions in granted forum access (by default all except guests), so please make sure the permission is enabled.
wpForo has a New User Control function in Antispam settings. It allows you to set a minimum number of posts user must have to be able to attach files. Please navigate to Dashboard > Forums > Tools admin page and manage the mentioned option in Antispam > New Registered user section. Set it 0 if you want to remove this limit.
the private msg doesn’t send the mail .
Please navigate to Dashboard > Forums > Settings > Addons > Private Messages subtab, make sure the Email Notification is enabled.
cross posting doesn’t work, either I posted on Post or Forum.
Here we'll need a bit more information to understand the problem. Could you please clarify a bit?
