I am trying to resolve a technical issue and am in conversation with various admins. However, my private messages keep being suspended, so I cannot reply to their queries. I am therefore posting this and flagging for a moderator in the hope they can lift the cap. The admin I am currently trying to contact is Jodi_S if you need to check that this is a legitimate request. She has responded to a message and I am unable to reply to her.
Very sorry to hear you are having issues with sending PMs. Can you please try clearing their cache & cookies. Also, can you tell us what times you're trying to send and getting the error so we can investigate please?
We have checked your account from here and there are no reasons as to why you can't send these messages.
Can you please provide us a screenshot of the error and the URL of the page you are on? Just to let you know, this would be a generic URL so if anyone click on it, they wouldn't be able to see the PM you are trying to send.
