Debug a Wordpress plugin...

Hi I need a PHP programmer who can debug/troubleshoot a plugin in Wordpress blog. The plugin is working, but its not functioning as it should be... I will explain what is the problem, and you'll need to investigate this using any developer tool like: Firebug (extension for firefox), or even by pressing F12 (on Chrome) then clicking 'Console' tab... or any other tool you might prefer... My guessing is that it's 1 of 2 things: -- A conflict with another plugin, but need to know which one and how to solve this issue? OR -- A file permission issue... i.e. file is not in the right permission, and this is causing the plugin not to function properly. Let me know & I'll reply with more info... Thanks, Mary
