Upgrading WP fails on VPS running PHP5

The normal things to check are folder permissions and the like.

Two questions:
1) Did you upgrade to 3.0.1 on those servers? Or were the sites migrated to that server already upgraded to version 3.0.1?

2) Have you put in a ticket to Liquid Web to get us to help identify the problem? If not, go ahead and we’ll see what we can do. If so, feel free to post or email me the ticket number, and I’ll take a look.

another things could be:

PHP isn’t configured to acept more than XX Megas of uploads
The runtime in every script in less than 1 minute
This is very common in hostings with php shared in multiples users,and disabled or strict config by security reasons

This cause my wordpress don’t update, the solution i’ve tested and work was:

Download all wordpress system into my pc, download all database, install PHP, and MySQL

And try to autoupdate from the local copy
When finish WP upgrade, upload it again to your hosting

Ok, this is how my php.ini is setup on my VPS:

upload_max_filesize = 10M
memory_limit = 256M

I also have problems upgrading plug-ins on these installs as well. While an entire WP upgrade will fail right at “Unpacking the update…” it seems that my plug-ins actually download as “tmp” files in my wp-content directory and fail to go any further than that.

Should my upload_max_filesize be increased?

Thanks

@liquid_squelch: 256 meg is too much memory to give every php job, unless you have gigs of RAM to spare. Try 64 meg, and then bump it just for WP with this line at the top of wp-config.php:

define(‘WP_MEMORY_LIMIT’, ‘128M’);

And check your permissions; that’s probably the cause of the plguins not finishing installing and stopping at the temp file stage:

Thanks for the info. I set my limit back to 64M in my php.ini and restarted Apache.

I’ve set my define(‘WP_MEMORY_LIMIT’, ‘128M’);

It seems I am getting closer to a solution. I now see this before everything halts:

The update process is starting. This process may take awhile on some hosts, so please be patient.

Enabling Maintenance mode…
Updating Plugin xxxxxx xxxxx xxx (1/1)

Maintenance mode does set. A tmp file is downloaded.
When I look at the file owners, I see (example) that the group is ‘Website1’ and the owner is ‘Website1’.

Thanks for the help. I see a light at the end of the tunnel and I am hoping it isn’t a train ??

Check your php error logs, too, wherever they happen to be on a hostgator VPS.

My error logs have been clean for the last 15 days.

php error logs or httpd error logs?

Httpd error logs are clean, and my php logs for the WP account doesn’t show anything other than [info] tags.

This is in my error_log when I attempt to do an upgrade:

And that is where it ends.

Thank you for the help so far.

Make an .htaccess file in wp-admin on the server with FTP and add this:

<IfModule mod_security.c>
SecFilterInheritance Off
</IfModule>

That turns off mod security just for wp-admin

Definitely getting closer here!!

I can now see an “upgrade” directory in my WP install.

There is a directory called wordpress-34.tmp, and sub-directories beyond that. But – there are no files.

The script still stalls at:

Update WordPress
Downloading update from https://www.ads-software.com/wordpress-3.0.4.zip…
Unpacking the update…

Thanks again – and Happy New Year.
