Hi i installed this script and followed the installation instruction: Installation Kootali Facebook Clone v1.5 Note: In order to run Kootali you need PHP5 and mod_rewrite enabled! 01. Upload all files from "UPLOAD" directlory to your server 02. CHMOD all files, folders and subfolders in /applications/content/ to 777 03. CHMOD all files, folders and subfolders in /application/language/ to 777 04. Create a MySQL database 05. Edit "/application/config/database.php" to match your MySQL database host, user, password, dbname 06. Edit the line $config['base_url'] in "/application/config/config.php" to match your site url 06. Import facebook.sql into your database. 07. Edit the line "RewriteBase /" in ".htaccess" Leave alone if you installed facebook into your server root or change to "RewriteBase /yoursubdir/" if installed in a subdirectory 08. You're done. 09. Go to http://www.yourdomain.com/admin/ and login with username "admin" and password "admin" p.s. If you can't save the config settings set permissions to all the files in "/applications/configs/" to 644 or 777 I did everything accept that i didn't even touch .htaccess which is RewriteEngine on RewriteBase / # if you installed facebook in a subdir use something like below and remove the line above # # RewriteBase /subdirectory/ RewriteRule ^admin/$ index.php/admin/login/ RewriteRule ^admin$ index.php/admin/login/ RewriteCond $1 !^(index\.php|application/images|application/scripts|application/css|application/content|application/settings|favicon.ico) RewriteRule ^(.*)$ index.php/$1 After this i go to http://www.test.ruslank.net/admin and try to login using login:admin and password: admin But system says : Login error. Invalid username. I don't know what i did wrong because i followed all the instructions, maybe somebody could help me i can even give u ftp access ... Thank you very much !
