我无法升级WordPress

Question

I transferred a 10 websites from one to another server. All sites use WordPress. When i tried to upgrade to WordPress 3.8.3 using update now link on the dashboard I am getting this error message.

Downloading update from https://downloads.wordpress.org/release/sr_RS/wordpress-3.8.3.zip…

Download failed.: Operation timed out after 300000 milliseconds with 523957 out of 6327138 bytes received

Installation Failed

Plugin Update works fine. WordPress just will not update. At all sites the same error.

On the old server it works fine. On the new server everything works except the update WordPress.

Answer 1

If your connection is slow, you can temporarily edit the file /wp-admin/includes/file.php. Search for the function function download_url( $url, $timeout = 300 ) and replace 300 with a larger number, e.g 3000. The file will be replaced after the WordPress has been updated.
