After installing 4.15b over 4.1 I get
An error occurred ! Unknown action
when choosing the following in the blog admin panel:
Design: Templates Preferences: General Preferences: Publishing Preferences: Entry Preferences: Comment Preferences: TrackBack Preferences: Registration Preferences: Spam Preferences: Web Services Tools: Plugins
Any idea what's going on here?
(I posted this once before, but it seems to be lost in the ether.)

OK, I wiped out the entire cgi-bin/MT folder and /mt-static folder, and created a new database.
Same results.
No such thing happening here... Did you check the permissions? Or maybe the transfer mode?
checked both - can't see a problem.
I'm downloading directly to the server now and will unzip it there to see whether that makes a difference :/
Still no love.
Looks like I need a different CMS solution.
Beta 5, same deal.
Anything here that could be a problem?

Weird. This thread isn't updating its last reply date.
Cindi - I am sorry for the delay in responding. That is a very odd issue that I have not heard anyone else report.
You should try an upgrade to the 4.2 release candidate, but if that does not fix your problem then I would like to confirm the URL you are on that is exhibiting this error, and also learn what plugins you have installed. There is a remote possibility of a plugin interfering with your UI.
Success!!
Except - what happened to the Styles menu?
To clarify - there does not seen to be a styles item in the design menu anymore.
The Styles item in the Design menu is a function of the Style Catcher plugin. Can you check to see if the Style Catcher plugin is enabled?
