Finally after a struggle of almost 2 hours to make everything work right and better I have successfully upgraded to Wordpress 2.1.x series without any problems.

First it took me 30 whole minutes to check my older plugins compatibility with the new Wordpress 2.1.x series and download the latest updated version of those plugins from the authors site and thankfully all of those plugins are fully compatible with Wordpress 2.1.x now and are running smoothly except for some odd ones that I shall discuss further.

As in my earlier post I have discussed some Worpress SEO Plugins, here I will do the same but specifically for the Wordpress 2.1.x series because a lot of Wordpress SEO Plugins are incompatible with this new series. A list of SEO Plugins for Wordpress 2.1.x is given below:

1 . Feedburner Feed Replacement

‘Forwards all feed traffic to Feedburner while letting through some important User-Agents’

The Plugin was updated on the author’s site to include compatibility for the Wordpress 2.1.x series

• Get Feedburner Feed Replacement

2 . Google XML Sitemaps

‘This generator will create a sitemaps.org compliant sitemap of your WordPress blog which is supported By Google, MSN Search and YAHOO’

This plugin has also been updated with a beta release to make it work with Wordpress 2.1.x and a lot of new plugin features have been added such as Yahoo Blog Update Notifier and Popularity Contest addon capability.

• Get Google XML Sitemaps

3 . Head META Description

‘Insert HTML META description tag: excerpt/content brief for post/Page, description for category, and blog tagline for everything else’

Though the development of this plugin has ceased and the plugin author is no longer updating it but if you have a bit of SEO knowledge you will know that you cannot live without this plugin if you want a good Search Engine Ranking. Besides the plugin is simple and does not need any update. Works smoothly with Wordpress 2.1.x as tested by me.

• Get Head META Description

4 . No Ping Wait
‘Speeds up posting by moving generic pings to execute-pings.php’

A must have in case you ping a large number of blog pinging/blog updating services. The plugin has not been updated for Wordpress 2.1.x but works smoothly with it and you might not find this plugin at its authors site so its available here at Sizlopedia.

5 . Popularity Contest

‘This will enable ranking of your posts by popularity; using the behavior of your visitors to determine each post’s popularity’

The Plugin caused a problem for me in the Admin section. A fatal memory-size-limit error caused when I tried to activate it in the Admin panel. I m not sure whether it was only for me or is it some bug in WP but I applied a small fix that made the plugin working smoothly. it requires adding a small line to admin-functions.php in your wp-admins folder. So if anyone of you experiences a similar fatal error and wants the solution just post in a comment and I will reply back with the solution.

Update: Read this carefully please. If you upload this plugin and activate it in your Wordpress 2.1.x you will mostly like get a fatal error pointing to admin-functions.php saying something like memory overload. Now you have two choices

1. Simply delete the plugin and not use it and everything will be back to normal
2. Use the plugin with a slight modification in your admin-functions.php

For those like me who choose to ‘use it’ follow this simple procedure:

Open your admin-functions.php in your {blog-directory}/wp-admin/admin-functions.php and add this line

ini_set(”memory_limit”,”16M”);

before

function write_post() {
$result = wp_write_post();
if( is_wp_error( $result ) )
wp_die( $result->get_error_message() );
else
return $result;
}

so it will finally look like this

ini_set(”memory_limit”,”16M”);
function write_post() {
$result = wp_write_post();
if( is_wp_error( $result ) )
wp_die( $result->get_error_message() );
else
return $result;
}

and save it and yourdone Now you can use the plugin without any error.

Technically speaking, this simple modification will increase the memory allocation of your admin-functions.php file which is initially set to 8MB.

6 . Share This

‘Let your visitors share a post/page with others. Supports e-mail and posting to social bookmarking sites’

The plugin works fine with Wordpress 2.1.x as I have tested myself. Just remember there is no need to upload the prototype.js file in the plugin folder to your Wordpress wp-includes directory. So no need to be confused and use the plugin as it is.

7 . Ultimate Tag Warrior

‘Ultimate Tag Warrior is a tagging plugin, that’s heavy on tag visualisation and its the heart of Wordpress users’

Actually at the authors site the plugin has not been updated for support with Wordpress 2.1.x so no need to go to the author’s site. But due to its heavy demand I have updated the plugin files to work with Wordpress 2.1.x and the plugin can be downloaded here at Sizlopedia.com

8 . WWW Redirect:
‘Redirects variations of identical domain requests to a consistent uri (i.e. http://abc.com to http://www.abc.com ). Useful to get a consistent Pagerank’

Th plugin is helpful to get a consistent Pagerank at with-www and without-www of your site URI. Plugin works best with Wordpress 2.1.x as tested by me.

• Get WWW Redirect

Upgrade Note: When you upgrade to Wordpress 2.1.x from an older version and do not see the Visual Rich Text Editor in the Write Post try deleting your browser cache and try again. Just a heads up to all as I experienced the same issue.
