No luck for me yet. I communicated directly with Kayapati who was very nice and willing to help but nothing he sent me has worked so far. As a last resort I manually edited my right sidebar PHP so that it would not say “sidebar widget goes here” nonsense and I’m just living with that for the time being. Going to check out the debugging links above
I’m having the exact same problem and it just started for me on my last update. I’m also using a Theme by Kayapati (electra) but in my case he doesn’t have a page for it anymore. Wondering what we can do! Stinks!
