How to make RewiteRule

Hi,
Do anyone know how to make rewriterule work in these cms?

I tried few times but I can't make it work.

because you did any mistake in .htaccess. Try to read manual about it. On my site all work good with rewriterule.

Can you paste here any simple code thats really working?

What exactly is necessary to you? What are you wanna rewrite? Example:
RewriteEngineOn
RewriteCond %{REQUEST_METHOD} ^TRACE
RewriteRule ^topic/([0-9]*)/?$ topic/index.php?id=$1 [L,QSA]

Try this. Hope I was help you.

you need to edit more function.php for all pages demo http://angels.10giay.us
