I was upgrading mu site to 2.8.4. I went to Site Admin -> Upgrade and hit Upgrade Site button. It worked for first 25 – 30 blogs and then died with message
Warning! Problem upgrading . Your server may not be able to connect to blogs running on it.
Error message: 200: Operation timed out after 3 seconds with 0 bytes received
This is what I did to fix my problem
I opened wp-admin/wpmu-upgrade-site.php and wp-includes/http.php
function &_getTransport( $args = array() ) {on line number 94 of wp-includes/http.php, wordpress tests different http request methods exist on your server during upgrade.
1st test was the culprit on my server which uses http_request method built into PHP. I guess this method was taking long time to resolve DNS and so it was timing out.
if ( true === WP_Http_ExtHttp::test($args) ) {
$working_transport['exthttp'] = new WP_Http_ExtHttp();
$blocking_transport[] = &$working_transport['exthttp'];
}I did comment out this test and let WordPress start with next one.
if ( true === WP_Http_Curl::test($args) ) {
$working_transport['curl'] = new WP_Http_Curl();
$blocking_transport[] = &$working_transport['curl'];
}And guess what? All 150 blogs were updated in a few minutes without any problem.
If even curl does not work for you, you can comment it out and move on to the next until WP upgrade site works for you.
Good Luck!
Hi there,
I’m a tech for a school district using WordPress MU with 236 blogs running on it. I encountered this error during the upgrade from 2.6.something to 2.8.6, and started digging around for an answer when I came across your tutorial. It made sense to me, so I tried it. Unfortunately, it didn’t solve my particular case.
I dug around a bit further and found that some of the users were using a theme called Book Love. It must not be compatible with the newer version of WordPress. According to my error_log for Apache2, it was causing errors:
# tail /var/log/apache2/error_log
“[Wed Dec 09 11:41:18 2009] [error] [client 10.1.1.23] PHP Parse error: syntax error, unexpected ‘}’ in /home/blogz/public_html/wp-content/themes/book-love-10/functions.php on line 28″
I went into the blog list, found the users blogs and clicked Edit. I removed book-love and Book Love entries, causing it to use the default theme, and WordPress was then able to upgrade the site past these blogs.

Hi, I recently started a bloghosting platform (based on wordpress MU) and when I stumbled your blog I paid attention to your theme (looking good) so I was wondering can you tell me is it custom made theme or one of those free ones? thanks in advance! regards, blogiskewl
I am using my own theme. I took ideas from different themes out there.
