I can't solve this problem. This started after I created a new sub domain. I can't update my plugins, install, delete.

During an update it says "successfully update". After I goes back to my plugin.php it needs to be update again. I can't delete the plugin even it says "successfully deleted". And also installing a new Plugin it says "successfully bla bla" but nothing happens when I go back (or refresh) my plugin.php.

I tried file permissions but no luck.

So I Update my plugin manually.

  • Did you check permissions on the plugins directory as well as every file and subdirectories, including files within those subdirectories?

It is either an issue with your file system or with your mysql database.

On some webhosting configurations, Wordpress automatic updates fail. In my experience, if it is not file permission, then it is an issue related to file ownership. Try the FTP method. Add the following lines in your wp-config.php

define('FS_METHOD', 'ftpext');
define('FTP_HOST', 'YOUR FTP HOST (without http:// or ftp://)');
define('FTP_SSL', false);

If still a no-go, see: http://codex.wordpress.org/Editing_wp-config.php#Override_of_default_file_permissions for alternative methods.


Also check that version of PHP in .htaccess is correct.

You should see a line like that:

AddHandler application/x-httpd-php55 .php

(In this case it's for PHP 5.5)

Note that you must do this at root of your WordPress site, not at root of your site.

  • @PieterGoosen Please just read the content: It's PHP 5.5

try the following code in your wp-config file before doing anything in plugin

 define('FS_METHOD', 'direct'); 
  • Please add an explanation to your answer: why could that solve the problem?
