Wow, I googled this forum while trying to solve a similar problem.
Perhaps the issue is not that subscribers can’t read, it might be something to do with having to have a different password for forums, for www.remarpro.com for wordpress.com etc. etc. I keep getting invalid username errors too, but I cannot register that username because it is already taken. It is taken by me. Your database is wordpresswide, but you can only use the username to access the product you signed up for. Here’s a hint, since you’re all wordpress, why don’t you make the login work across the board, and save everyone the hassle of figuring out the magic system you’ve built. Dicks? That’s putting it very nicely. Way to maintain your composure davinahaisell.
