WordPress Automatic Upgrade plugin update

Lots and lots of bugs and sleepless nights and no paid work later. Here is the next version of WPAU. I have fixed almost all of the bugs you have reported which I heartily thank each and every one of you for. Here is the NextG version of the plugin which works on most of the servers that have different users for FTP and web.Here is what I mean by that

On some shared servers the webserver (Apache) is the same for multiple user and in those cases the Apache user was not allowed to access files uploaded using a FTP client. To overcome the situation I added a preliminary check where it checks if the plugin is able to update the site or not.

If the error is due to FTP user and webuser being different you will be asked for your FTP credentials. We do not save any of this information with us and the information will be discarded at the end of the upgrade.

This is necessary if you need to run a automatic upgrade on your server, without this the information the plugin will not run.

What do we do with the FTP information?

With the FTP information you provide WPAU will change file permissions so that WPAU can write the files to your server. Once the upgrade is over WPAU will automatically change the permissions back to read only.

This step has been added so that you do not have to do the permission change manually. Only in certain rare cases will it fail to upgrade permission’s and ask you to do so manually.

Here are some of the bug fixes for the latest version.

  • Runs a premilinary check to see if your server is compatible so that WPAU can run
  • Advices to clear backups from past upgrades
  • Fixed errors for virtually hosted sites
  • Automatically change permissions for upgrade after asking FTP credentials
  • Fixed bug where DB error was reported when WPAU used to fail
  • Fixed bug where you could not see log when the WPAU used to fail
  • Updated FAQ to add the new questions
  • Fixed issues to only backup and upgrade core WP files (This was a issue when WP was hosted in root directory)
  • Fixed a issue where wp_redirect was not working due to header file already being included in the plugin
  • Cleaned up the code to make it better

That’s it folks, all your bugs and abuses are welcome since it helps me make this plugin better. I hope you will in future use this plugin to upgrade your wordpress installation without any errors and headaches.

Also with so much love and people reporting bugs I am so glad that I have been able to fix most of

  2. Delete the index.php file.
  3. Rename the index.php.wpau.bak file to index.php

Performing these steps should remove the maintenance mode message.

Why does the plugin say that it cannot upgrade my site?

We run preliminary checks to see if the plugin can run well with your site. Only in certain cases it will tell you that it cannot upgrade your site because the functionality of the plugin depends on it.

Why I am asked for my FTP credentials?

Initially we try to check whether your WordPress installation is writable or not. If we find that its not writable we ask you for you FTP credentials so that we can do the necessary things to make it


What do you do when you get my FTP credentials?

First of all for security reasons we do not store your FTP Credentials. We only use it to change the file permission so that the plugin can run normally.

Once we run the appropriate steps to check that everything is alright only then will the plugin continue the further steps.

What do you do when I give you my FTP credentials?

When you provide us with your FTP credentials we log into your site using FTP and change the permissions on files and directories such that it can be written by a file running on your server.

If you are asking in regards to WPAU absolutely. In order to complete the automatic upgrade we need write permissions to your site.

When will be asked for my FTP credentials and why?

You will only be asked for your FTP credentials when we cannot write to your server.


Some shared servers run different the webserver and apache as different users which is for security reason. In that case when we using the webserver cannot modify the files you have uploaded using a

FTP client.

In such a case we could ask you to do the steps required manually, but in the sense of automatic we want to make sure your upgrade is really automatic. When you provide us with those details we do

not store it (though we may ask you for this everytime we determine your server is unaccesible for us) we maintain a security level which no other plugins can exploit over and above the one

WordPress provides.

We are very much that this plugin should be automatic and only if our preliminary checks fail initially we will ask you for the FTP credentials. You will never be asked for that when the plugin can run

without the credentials.

If I am running on a server where FTP user and webserver user are different will I be able to overwrite / delete files using FTP

Yes absolutely. The plugin makes sure that whichever files it writes can be deleted by the user without having to contact the system administrator.

Why don’t you provide a option for me to upload the version I want?

Couple of things here. a. You should always upgrade to the latest version provided by WordPress. b. I do not want users to upload files that requires me to do multiple validations. The WordPress files that this plugin downloads is the best one I could use.

  1. I am having the issue where the site got stuck on maintenance mode. I followed the instructions:

    Login to your site using FTP.
    Delete the index.php file.
    Rename the index.php.wpau.bak file to index.php
    Performing these steps should remove the maintenance mode message.

    It got rid of the message indicating that the site is in mailtenance mode, however I am simply left with a blank white page with no data.

    Has anyone else run into this issue? and is there a solution?

  2. I tried your plugin: everything goes well, but at the end the blog was still in maintenance mode so I tried to follow the FAQ, but when I connect with FTP there was no index.php.wpau.bak file…
    I replaced the index.php with the backup one and all comes back, but I want to file this bug to you.

  3. Pingback: Daily Links
  4. I went from 2.2.2 to 2.2.3 no problem. On another blog, set up the same way on the same server but in a different subfolder off my account root (/site1 and /site2, you get the idea), my upgrade of the v2.0.6 blog takes me after the “ready to roll” page to a 404 page on my blog and dies.

    I have no idea where to look to start troubleshooting this. I was choosing the “manual” step-through-it-one-step-at-a-time link to proceed.

    Ideas? Thoughts? It really was pretty slick the first time I ran it, and I’m kinda bummed it’s effing up on this one. :(

    Thanks for any help!


  5. Hi Keith, thanks for the plugin, its really helpful!

    One tip for the people that still get the FATAL error when trying to activate the plugin even adding Britt’s tip to increase “memory_limit”.
    You also need to have Short Open Tags enabled on your php (Keith, if you remove the use of short open tags, it will improve the compatibility for different php installations).
    You can add Short Open Tags support creating an .htaccess file on your wordpress admin directory (wp-admin) with the line:
    php_flag short_open_tag on

    I hope it helps!
