My title has 4 P's!
So, yeah, I just updated to 3.4 and now my password protected posts do not work.
I input the right password, and then wordpress delivers me to my login page.
My users have all had the same problem.
This was never an issue in the older version, so I looked around the forum and found some suggestions, such as deactivating or deleting plugins, which I have done, and still no progress.
If anybody else has the same problem, please comment so we can all come to a good solution. If anybody has any idea on how to fix this, please, I'm all ears. (or eyes...)
