WordPress site down after upgrade

Not sure why that would happen. When you say down, what exactly happened?

Website came back with a timeout message.

Below I found in the logfile of the server

[Mon Feb 04 16:43:44 2013] [warn] (103)Software caused connection abort: mod_fcgid: ap_pass_brigade failed in handle_request function
[Mon Feb 04 16:44:32 2013] [warn] (110)Connection timed out: mod_fcgid: ap_pass_brigade failed in handle_request function

I’d contact your web host about this, I don’t think it’s a problem with the plugin.

You can not contact my webhost because we are the webhost of our own servers.

I’m sure it’s a problem with this plugin, just upgraded this plugun on another website and server and the same thing happens, deactivate the plugin solved the problem again.

It’s something to do with how your server is setup. This is the first case of this happening (that I know of). Some setting in apache or php on your server is causing this, the plugin is not at fault. I do not know what the fix is but some googling should clear it up.

Same thing happened to me where I updated this plug-in on one of our development sites, and it took the entire install down. Had to go in, deactivate every plug-in, then restore everything one by one until I found the culprit. I have since had to revert back to version 2.9.8 in order to get it back into the site.

Strange…can you guys let me know your apache and php versions?

It’s running on a Plesk server in FastCGI mode with PHP 5.3.16-1

Apache Version 2.2.22
PHP Version 5.3.14

Also, if it matters, I”m running cPanel on my server

Apache Version Apache/2.2.22 (Unix)

Have you tried manually installing the plugin?

Yes same problem, when use an older version the problem is gone.

So the error occurs during activation? Is it a 500 error?

Finaly after a timeout there is an 500 error on the screen.
