SEF/.htaccess issues - Joomla! Forum - community, help and support

hi, , sorry english.
i've searched forum same issue haven't found same issue.
i used joomla 2.5 in last year without problems , have removed cms, installed joomla 3.0 , rebuilt site, updating old templates , plugins i've developed.
well, long worked offline, fixing minor issues, sef worked perfectly, when i've publish website started having problem menus.
when click on link in top menu, server reload actual .php page , not target one.
i've check joomla settings seo/sef , .htaccess too, consulting many guides online. seems ok, sef settings works when turn offline website, or when turn off sef option.

my website: http://theburningdogma.com
my .htaccess file (i have removed commented lines make topic shorter):

code: select all

#options +followsymlinks

rewriteengine on

rewritecond %{query_string} base64_encode[^(]*\([^)]*\) [or]
rewritecond %{query_string} (<|%3c)([^s]*s)+cript.*(>|%3e) [nc,or]
rewritecond %{query_string} globals(=|\[|\%[0-9a-z]{0,2}) [or]
rewritecond %{query_string} _request(=|\[|\%[0-9a-z]{0,2})
rewriterule .* index.php [f]

rewritebase /

rewriterule .* - [e=http_authorization:%{http:authorization}]
rewritecond %{request_uri} !^/index\.php
rewritecond %{request_uri} /component/|(/[^.]*|\.(php|html?|feed|pdf|vcf|raw))$ [nc]
rewritecond %{request_filename} !-f
rewritecond %{request_filename} !-d
rewriterule .* index.php [l]


i've tried comment , uncomment "options +followsymlinks" , "rewritebase /" (i've installed joomla in main directory "public_html")

so, ask self , forum, why joomla 2.5 works perfectly, , sef works when site offline? think problem of configuration , not server (litespeed webserver linux, hosted on netsons.net)

have checked components of plugins messing rewriting? try disabling them , see if resolves issue.
