IF you have basic DNS and HTML knowledge you can do these easy steps:

  1. add to your dns Aliases (A records) with the name cache1.yourdomain.com and cache2.yourdomain.com in order to point to the same place as www.yourdomain.com
  2. edit your theme header.php file and change the adresses of the css and js files to cache1.yourdomain.com. do this with the plugins also.
  3. go to your media options in wordpress and put full URL path to files to cache2.yourdomain.com, as seen below:

cache

This is all. This can be easily done using CDN rewrites after completing step one.

Here’s my wish list, in case anybody from Microsoft is listening:

  1. fixing the jpg-png transformation bug
  2. an option for a cropped thumbnail.
  3. an option for choosing my own thumbnail name. wordpress has the -100×100.jpg naming system, wlw has _thumb.jpg system. so wlw is uploading two files instead of one.

It’s not much, but it will really help a lot of people.

Google has a problem with that http://www.valipetcu.com/2011/removing-wordpress-version-from-header-google-has-a-problem-with-that.html http://www.valipetcu.com/2011/removing-wordpress-version-from-header-google-has-a-problem-with-that.html#comments Fri, 25 Nov 2011 05:59:07 +0000 vali petcu http://www.valipetcu.com/2011/removing-wordpress-version-from-header-google-has-a-problem-with-that.html

This is what i got from Webmasters Tools. The thing is i do have the latest version of WordPress, but i removed that announcement from the header, in order to protect myself from attacks.

remove_action(‘wp_head’, ‘wp_generator’);

“Invalid Server Response – The response to the metaWeblog.newPost method received from the weblog server was invalid: Invalid response document returned from XmlRpc server.” .

The error in the log is

PHP Warning: strpos() [<a href='function.strpos'>function.strpos</a>]: Empty delimiter in /usr/home/zoso/www/zoso.ro/wp-includes/class-wp-xmlrpc-server.php on line 2379

I just removed the line 2379 from wp-includes/class-wp-xmlrpc-server.php

if ( strpos( $post_content, $file->guid ) !== false )

And everything is back to normal.

I was using W3TC up until a couple of days ago. The plugin has many great features, but does a poor job halding post pages with comments and the users get annoyed when they post a comment and the page goes blank.

WP-SC is a much better alternative. Much easier to set up and does a better job. I kept the image and browser cache .htaccess rules from W3TC and put the plugin to work. After a full day the stats are looking better and the server load dropped with about 20%:

WP-Cache (1.61MB) » 164 Cached Pages
WP-Super-Cache (170.92MB) » 3834 Cached Pages

Some say Hyper-Cache is better, but i never got it to work properly.
