URl prefixed with 'www' causes the 'token mismatch' error.

When prefixing the URL (int the browser) with 'www' we got the 'tiken mismatch error' and the MyBB content is not displayed.

The plugin works in two steps:

• first step is to hit the MyBB engine, prepare the MyBB output page and get the Wordpress wraper page
• second step is to get the MyBB content (output page)

The MyBB output page prepared in the first step is stored in user's php session. This content is fetched in the second step.Second step hits the server with no 'www' prefix. First step may hit the server with or without 'www' prefix; depends on user. PHP core is 'www prefix'-sensitive while creating user sessions: it may create different user sessions for both steps; which causes the MyBB content not available (token mismatch error) when using 'www' prefix.
