SEF problem adding /Contacts/ to url and showing 404 error - Joomla! Forum - community, help and support

i'm using joomla 2.5.8 on site http://www.edit365.com.au , "#404 category not found" if enable sef (with url rewriting , without it). related issue adds /contacts/ url.

e.g. if url "test" should http://www.edit365.com.au/test, or http://www.edit365.com.au/index.php/test (with mod_rewrite off). displays http://www.edit365.com.au/contacts/test, or http://www.edit365.com.au/index.php/contacts/test.

all urls i've mentioned display 404 error, no matter what.

this .htaccess info:

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 removed # commented lines make quicker read.

note: i've tried 2 different templates , doesn't work of them.
