If no tag shows up on her profile saying that she's blocked, it's possible that she might have been caught up in an IP block. When a logged in user is using an IP that has been blocked, they can't edit either. Though when they switch IP, they will be able to edit again. Such an IP block also doesn't show up for others on the account, as it is not the account that's blocked.

However, that's all just a general explanation. If she really wants more concrete help, then she should share the block ID number that she receives. That way, staff/VSTF/helpers can see what exactly has been blocked and provide a better explanation if necessary and opportune.
