I did notice in the span class of the post link there is a weird output:
“<!– wpcuFPN Unknown field: –>”

I was forced to rollback to 2.8 and now i can embed properly again.
I resolved this. The plugin that was causing the issue was Captcha. I took it off the login form and you can successfully log in with the account you created.
I encountered the same problem today also when I got a notice for the update. Updated it and couldn’t enter “Installed Plugins” or core update section because I got the same fatal error as you guys.
After commenting out line 160, it works and the update notice went away. I didn’t notice the icons disappearing though.
