Hi there. I am having the same problem. It's not an issue on a network level. The situation is as follows: The contact form 7 integration always was a free plugin and it was installed as such on my site. It still shows it as a free plugin in the newsletter backend too. When I try to update it I get a forbidden like the OP. When I try to download it direct and update it it is listed as a PAID plugin now and won't let me download without paying. So, either there is a mixup somewhere or you are risking 1000s of users to stay with an old version (potentially dangerous) because they can't no longer update because payment is now required. Please advice.
