Look at my site: www.pro-datum.com It looks different in internet explorer 9 and mozilla firefox. Text not showing up. It is ecopro theme. can anybody tells me why?

You have quite a few markup errors: http://validator.w3.org/check?uri=http%3A%2F%2Fpro-datum.com%2F&charset=%28detect+automatically%29&doctype=Inline&group=0 Different browsers handle invalid markup differently, so I would start there.

So what should I do? I need to check every single error?

I see a lot of "element P undefined" errors. Perhaps you should start by correcting those ones (making sure that

<p>

is at the start and

</p>

is at the end)

IT should be small p or capital P?

It should be lowercase.
