I have "Clear" theme (Invent Group, v1.3) and since the the WP upgrade I've lost control of widgets and media import. The buttons don't work.
Support: It looks like Invent Group has changed or disappeared, I'm not sure. Google leads me to dead ends. A closed wp-forum on the same issue 11 months ago posted a contact email address: email@example.com, it's a dead end also. So any hopes of getting patch/fix from the developer seems impossible, unless someone knows an "in".
I'm not sure what the issue is specifically, but I'd like to know what I can do to mend this problem with this theme and WP.
