 * We typically don’t recommend free hosting providers around here, as they often
   offer crippled servers that prevent WordPress from functioning properly.
 * There are a few [recommended hosting providers](https://wordpress.org/hosting/),
   and if you really want a free blog, try [WordPress.com](http://wordpress.com/)
   instead.
 * If that’s the only plugin that won’t install for you, your free hosting provider
   may have blocked the upload of specific file types, like .mo.

 * That looks like a huge mess, those aren’t normal WordPress rewrite rules.
 * We really can’t support free hosting providers around here due the amount of 
   things they break or alter just to keep the costs minimal for themselves. Most
   of the time, anything broken with WordPress on a free hosting provider is because
   the server is poorly configured.
 * You may be able to install plugins and themes manually:

 * The plugin’s .php file, not WordPress’s plugins.php file.

 * yes. the plugin’s PHP works fine. ive added wp super cache through admin dashboard.
   its failed but when i check wp-content/plugin/ , it was there. but not listed
   in Plugin listing in admin dashboard.

 * Right, but did you open the plugin’s main .php file in a plain text editor via
   your FTP client to see if there was any random code at the top?
 * WordPress hides the plugins for very good reasons sometimes.
