upgrade to WP 2.9 – if auto-upgrade doesn’t go auto

Yesterday, I tried to auto-upgrade to WP 2.9. I pressed the respective button and Safari presented a new page indicating a download process. Unfortunately, the process suddenly finished – with no upgrade at all.

In case you try to auto-upgrade too, here is the way to manage the task anyway:

  • - First, download the WP 2.9 upgrade archive file [download link]
  • - Unpack the archive file to a local volume [your Mac OS X system unpacks automatically]
  • - Start you FTP-client and connect to your WP virtual host [for Mac OS X, you might wish to download the FTP client Cyberduck]
  • - Finally select all files within the archive and drag them to you FTP-client’s window

Now, it’s time to run the real upgrade process. Enter this URL

http://www.yourSiteName.com/wp-admin/upgrade.php

or, if WP is installed in a folder named e.g. myBlog, enter this URL

http://www.yourSiteName.com/myBlog/wp-admin/upgrade.php

At this point, you might end up with a blank page or one, which indicates a HTTP error 500. In this case, have a look at my previous post, which provides a solution regarding PHP setting of certain providers (namely 1&1).

After that, enter one of the above URLs again. WordPress should now present a small upgrade wizard, which explains the next steps to do. A typical upgrade process should finish within a few minutes (at least mine finished soon).

Get schema-free within minutes using MongoDB

For other types of application, this approach tends to make development complicated.

Upgraded to WP 2.9 – and ended up with an HTTP error 500

After quite some time, I visited this my blog to apply the most recent Wordpress upgrade, the 2.9 release.

After the I finished the upgrade, the front-end rendered fine, while I constantly got an error from with ADMIN site: HTTP 500 error.

In case your site runs on a server hosted by 1&1 too, you have to do two things to get ADMIN running again:

1. Create a php.ini in WP’s root directoy and add this single line of text:

memory=20MB

2. Edit WP’s .htaccess file  and add

AddType x-mapp-php5 .php

as the very first line.
