Hi,

Not all of my themes had settings but as of this morning, all my themes are without settings.
It just shows customization and manage widgets.

I am unable to update my logo. Any help is appreciated.

There used to be problems in case theme incorrectly adds links into Appearance menu and best thing to do is to search for hook adding menu links into osclass and make sure it is added into 'init' and not 'header' hook.
