Stuck in SEF URL limbo (server error after saving anything) - Joomla! Forum - community, help and support

alright here deal... of right can not save in global configuration. seo settings stuck @ "sef urls: yes", else set "no". when attempting save changes following internal server error: "the website encountered error while retrieving http://.../administrator/index.php?option=com_config.

now here interesting thing. if make changes anywhere else in backend of site (ie. create\delete article, adjust template parameter, etc). same error message (with different path) after refreshing the changes saved.

as far know changed affected files original state: htaccess.txt , configuration.php. changes made when attempting enable url rewriting include following: (they have been reverted original value)

configuration.php
set var $live_site ''

htaccess.txt
set .htaccess htaccess.txt
added "#" before "rewrite base /"

...thats changes i've done before got server errors... dont know know if stuck in cache or not, can not clear server error.

thanks assistance!

configuration.php
set these values 0

code: select all

public $sef = '0';
public $sef_rewrite = '0';
public $sef_suffix = '0';
