The Crucial Blog - Archive
Upgrading Wordpress from 2.3.3 to 2.5
1. Backup all the relevant wordpress files.
2. Backup your MySQL database
mysqldump crucialu_blog > crucialu_blog.sql
3. Upgrade necessary plugins and once done, login to Wordpress as admin and deactivate all plugins.
Dashboard ->> Plugins ->> Deactivate All Plugins
4. Download the latest wordpress.
wget http://wordpress.org/latest.tar.gz
5. Untar the file and rename it to /blog
6. Copy the wp-config.php from the backup
cp -p blog.bkp/wp-config.php blog/
7. Take the URL http://www.crucial.com.au/blog/wp-admin/upgrade.php and Click on “Upgrade WordPress”
Click on “Continue” to complete the upgrade.
8. Copy the custom files /folder from backup to the new installation folder
cp -rpf blog.bkp/wp-content/* blog/wp-content/
9. Login to wordpress as admin and Activate the required plugins.
Dashboard ->> Plugins
After upgrade, if you are getting a blank screen while accessing the site, you might have forgotten to copy the themes and templates. Go to step 8 in that case.

404 Error when to accessing /wp-admin/admin-ajax.php
When you receive this error:ForbiddenYou don’t have permission to access /wp-admin/admin-ajax.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
If you are receiving this error, then its likely you have mod_security installed on your server, and you will need to update your mod_security rules.
Find the following in your mod_security configuration:
Only accept request encodings we know how to handle # we exclude GET requests from this because some(automated) # clients supply "text/html" as Content-Type SecFilterSelective REQUEST_METHOD "!^(GET|HEAD)$" chain SecFilterSelective HTTP_Content-Type "!(^application/x-www-form-urlencoded$|^multipart/form-data;|^text/xml;)"
Change it to:
# Only accept request encodings we know how to handle
# we exclude GET requests from this because some (automated)
# clients supply “text/html” as Content-Type
SecFilterSelective REQUEST_METHOD “!^(GET|HEAD)$” chain
SecFilterSelective HTTP_Content-Type “!(^application/x-www-form-urlencoded;|^multipart/form-data;|^text/xml;)”
If you don’t have access to mod_security configuration (i.e. you are not the administrator of the server), then you can add the following to a .htaccess file for your site:

SecFilterInheritance Off
</IfModule>
