We have noticed that the WordPress Plugin AdBlock Blocker does not work properly. On the surface it seems to only be a minor ajax conflict which is causing the admin menu to not drop down or allow the admin to tick all pages (bulk selection) when viewing pages.
We need you to firstly address the problem with the plugin that is causing the admin area to fail. We then need you to thoroughly test the plugin to ensure that all other features within the plugin are working as they should.
We can provide you with access to a cpanel hosting account and test WordPress install for you to use should you need it.
We are always looking for new programmers to work with us. If we are happy with your price and the work that you do, we will select you as our chosen developer and give you first refusal of all future projects that we post on freelancer.com.
You can download the plugin here: http://wordpress.org/extend/plugins/wordpress-adblock-blocker/
You should test it with the latest version of WordPress as well as the latest beta version of WordPress to ensure that it will not break as soon as the next WordPress version is released.
