Theme not working

but they aren’t working, they show as if they are not compatible. I have reinstalled the theme, but it didn’t help.

What other theme than Twenty Eleven are you referring to?

Have you contacted that theme’s developers of this issue?

Excellent.

Sorry, WordPress forums do not support commercial themes.

These are your errors;
