Thank you for input Carlison...
htaccess code is given below and my guess is also that problem lies here in these codes because
1-I have fixed my site to https mode using htaccess codes file
2-osclasswizards permalinks code also needs to be put in htaccess file
I am sure - the way I put code may not be perfect specially found ALL Listing issue as u mentioned and some coder can rectify issue and provide correct code .
Current code in htaccess is given below
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# Prevent Apache from serving .htaccess files:
<FilesMatch "^\.htaccess">
Order allow,deny
Deny from all
</FilesMatch>
RewriteEngine on
RewriteCond %{HTTPS} !=on
RewriteRule (.*)

Thanks
