Help needed with text editor - I'm cracking up!! - Joomla! Forum - community, help and support

i having weird problems of text editors come standard joomla install. using version 1.0.13 , may have missed new joomla.

basically, can save new article / edit existing article if have no formatting applied text. means can't bold, centre, underline etc. or carriage return without kicking me out , taking me homepage. have tried using no wysiwyg editor , tinymce wysiwyg editor , not defining editor results in same. can update subject , other perameters without problem, try format text goes horribly wrong. kicks me out if use html editor format text. have tried installing text editor - joomlafck worse , won't let me save unformatted text - again happening in body text, saving titles etc. fine.

i have set 5 sites different sites , happens on of them.

i have looked on forums , can't see problems same mine although have tried other suggestions made far including:
going configuration.php file , making sure url defined $mosconfig_live_site valid url (such http://www.yoursite.com) - checked , ours correct.

i tried suggestion (http://forum.joomla.org/index.php/topic,181755.0.html) can't find 'gap after ssl check , before "require_once( '../includes/joomla.php' );": ' mentioned.
i have searched in both index.php , index2.php within administration folder, cannot find reference ssl @ in index.php (perhaps problem?) , although can see section mentioned in index2.php not sure slot in code in. section says:
to apply fix, open index.php , index2.php in administrator folder, , insert following in gap after ssl check , before "require_once( '../includes/joomla.php' );":

i have copied code below - can enlighten me??? help!

ssl check - $http_host returns :
$http_host = explode(':', $_server['http_host'] );
if( (!empty( $_server['https'] ) && strtolower( $_server['https'] ) != 'off' || isset( $http_host[1] ) && $http_host[1] == 443) && substr( $mosconfig_live_site, 0, 8 ) != 'https://' ) {
$mosconfig_live_site = 'https://'.substr( $mosconfig_live_site, 7 );
}

require_once( $mosconfig_absolute_path . '/includes/joomla.php' );

just sure. have applied patch?
