Problem uploading wordpress plugin

I use the admin panel and it works for other plugins but some of them say

Unpacking the package.

Could not copy file /public_html/wp-content/upgrade/wordspinner/wordspinner/wordspinner.php


What can I do to fix it?

 

Tray to upload plugin directly thought FTP to wp-content/plugins and then install it manualy in admin panel > plugins

 

chmod the directory to 777 , if not..try to do it manually. you might not have enough permission.

 

Also, if you add the following lines to wp-config, you will not be asked for password everytime you install/update a plugin:

putenv('TMPDIR=' . ini_get('upload_tmp_dir'));
/** Override default file permissions */
if(is_admin()) {
add_filter('filesystem_method', create_function('$a', 'return "direct";' ));
define( 'FS_CHMOD_DIR', 0751 );
}

Code (markup):
