when i instal joomla it was working perfect but after the hosting had the problem with PHP and SQL no joomla is tellin me that the file are unwriteable (like config.php, or language.php) can someone help find a solution for this
If you are still having issues changing the CHMOD of the folders/files to 777, let me know.
It is not recommanded to leave the configuration.php file in CHMOD 777. once you modify your site configuration, set it back to unwriteble ( in Joomla Admin).
