Rfblanchard,
The problem could have been caused by an incompatibility with another plugin. But beyond that I am not sure what exactly would cause it. if you have (since posting this request so long ago) found the cause for the error, please let me know so I can either correct it in future editions or post a list of incompatible plugins with it.
I have the same issue. After installing and activating the plugin I get the same error message and the option page is blank.
call_user_func_array() expects parameter 1 to be a valid callback, function ‘BrowserBlocker_Options_Page’ not found or invalid function name in …/wp-includes/plugin.php on line 403
these are the plugins I have:
Blog Copyright (by BTE)
CMS Tree Page View
Dynamic 404 Page
Easy Contact Forms
Quick Page/Post Redirect DEV
Simple Fields
Ultimate Coming Soon Page
Have you got anyone of these plugins installed rfblanchard?
no, I don’t have any of those plugins installed. Using Firefox 15 and wp 3.4.1 I still get this error as of today:
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘BrowserBlocker_Options_Page’ was given in C:\Documents and Settings\rblanchard\Sites\wptest1\wp-includes\plugin.php on line 403
Same error here

Switched to 2010 theme and disabled all other plugins – same issue. Can’t get to settings page.

Well, I just released the 0.5.6 version of the Browser Blocker Plugin, unfortunately I have not been able to replicate the issue discussed on this forum, but based on the error feedback I have made some changes to the activation code that I hope will address the issue.
Please respond and let me know if you are still experiencing the issue or not.
Hey,
I had the same issue. It seems you often didn’t open the php parts in your .php files correctly. You used “<?” as opening tag but it has to be “<?php” after changing this in all your files it worked good for me!
Hope that helps
