Plugin and Firefox 6 mismatch

I have just put up a new WP site and the Membership plugin 2.0.6 on Wordpress 3.2.1 doesn't work with Firefox 6.0 even in Safe Mode at least for Twenty Eleven and Twenty Ten themes. The Dashboard is visible as normal.

It works for other sites that I have.

The plugins I have active are:Bad Behavior, en-GB localisation, Subscribe2, Twenty Eleven Theme Extensions and UK Time. There are others but they are not activated.

I switched all plugins off and it works and switched them on one by one. The only one to repeat the problem is Membership. It works with Chrome, IE and earlier Firefoxes. I don't know whether this is a plugin or browser issue.

I have switched Membership off for the moment.:slight_frown:

Has anyone seen this before?

    The site is

    At the moment I have disabled the Membership plugin but if I enable it, the source of the site is just:

    <!DOCTYPE html>
    <!--[if IE 6]>
    <html id="ie6" dir="ltr" lang="en-US">
    <!--[if IE 7]>
    <html id="ie7" dir="ltr" lang="en-US">
    <!--[if IE 8]>
    <html id="ie8" dir="ltr" lang="en-US">
    <!--[if !(IE 6) | !(IE 7) | !(IE 8)  ]><!-->
    <html dir="ltr" lang="en-US">
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width" />
    <title>Mortgage Free in Three | Just another WordPress site</title>
    <link rel="profile" href="" />
    <link rel="stylesheet" type="text/css" media="all" href="" />
    <link rel="pingback" href="" />
    <!--[if lt IE 9]>
    <script src="" type="text/javascript"></script>

    Ie there are <html>, <head>, opening <meta> statements, the <title> and some <links> plus the usual IE exceptions.

    Yet the dashboard is displayed as usual and other sites that have the membership plugin - even the same set of plugins - seems to work.

    I can clone the site into a dev site and enable a login for you to try if that will make it easier.

    Hmm. The same now happens with this site and Chrome 11.0.696.65 - I can see the front end of the site with Membership disabled but not with it enabled! The same code is visible. And in IE. The issue appears to arise if I enable the Membership plugin then go to the site within the same browser session.

    I can't see what is different on this site and others. If I can't see what it is that is doing this in the next day or so, I will build a cloned site and let you know the user/password.....

    Looking in the logs I see the following message (this is from yesterday so I should have looked there first :oops:

    PHP Fatal error: Call to undefined method WP_User::WP_User() blah blah in /wp-content/plugins/membership/membershipincludes/classes/class.membership.php on line 23

    I am running PHP 5.3.2-1ubuntu4.9 with Suhosin-Patch.

    I now have a dev site for you to play with if you want... email me for user and password.

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
