Internet Explorer not compatable with my site?

Start here: https://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fconstant-conflict.org%2F

Thanks. But Im still a little confused on all that?

I linked to the result of an automated validator checking whether your HTML is valid.

Basically, it just means you need to take a close look at your HTML output and see if it’s all correct. The validator says it found 17 errors, although in truth there are probably fewer. (Often a single error will cause a cascade of errors in the validator.)

And take a look at the DOCTYPE warning at the top of the validator output.

If you successfully validate, and you still have this problem, post another reply.
