No worries. Bugs happen.
I am glad you were able to release a fix this fast.
Thank you, Robin!
You linked the wrong thread in the new trac ticket.
Chuckie, try logging in using the standard WordPress login page and rollback to the previous version.
https://publictalksoftware.co.uk/wp-login.php
You can get older versions from the Advanced page on WordPress.org.
You can find a dropdown with previous versions at the bottom of this page.
https://wordpress.org/plugins/bbpress/advanced/
Once you download the version you want, upload the ZIP archive under Plugins > Add New.
You will be asked to overwrite the existing plugin. Click Yes, and you are back to normal.
I just did a test with the LearnDash integration addon disabled, and it made no difference.
The issue is caused by bbPress.
I’m not using any other addon for bbPress, but I do have LearnDash and their bbPress integration addon.
bbPress Integration
Hello, Robin!
I tried all the steps you mentioned before opening this ticket.
I cleared both the page and object caches and resaved the permalink rules in case this was causing the 404 errors. (although permalink issues would cause problems regardless of the logged-in status)
In addition to the 404 errors, pages containing queries, like the Blog page or post-type archive pages, load as they should, with 200 OK status, but do not display any content. (the queries return null)
Reverting to bbPress 2.6.9 solves the issue.
And as I mentioned, this only happens for anonymous visitors. For administrators and logged-in users the pages work as expected.
