bbPress forum plugin, login, registration 401 authentication error workaround
I've seen a few posts showing that some people are having issues with users getting registered and/or logged in when they are using the bbPress forum plugin on their WA hosted sites. It seems quite a few are getting the annoying error:
"401 Authentication Required - This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required."
From what I've read, this isn't something limited to just WA hosted sites and has to do with some type of security setting that hosts have implemented.
I was going to submit a trouble ticket and then decided to tinker around a little bit instead. :)
It seems, at least in my case, that this error was only happening when I was using the bbPress widget for registration and login.
So I decided to try adding the Meta widget to the sidebar and see if that would let a new user register, login, and post. It did.
But I don't like that Meta widget, lol, so I decided to find a simple sidebar login widget https://wordpress.org/plugins/sidebar-login/ and things seem to be working fine.
New users can now register, login, and post without issue.
If you're having this issue with bbPress and decide to try this, let me know if it works for you.
Also, if you had support take care of the issue, please share what the issue is if you know.
Good luck and have a great day.
