It doesn't affect the public site at all, and it's not activated either. I would think a similarly benign plugin could be included, just so there is something there. </p> http://bbpress.org/forums/topic/installation-problem-cannot-modify-header-information#post-13039 Sun, 06 Jan 2008 06:04:17 +0000 fel64 13039@http://bbpress.org/forums/ <p>No, from the PHP docu <code>glob</code> only returns false when it encounters an error. No files found makes it return an empty array. (I don't have any underscored files and it works for me, too.)</p> <p>But I agree with you, those folders should be in there by default. What plugins could be included that could be interesting to everyone?

I don't follow the code exactly, but further up in that file, it defines BBPLUGINDIR if it's not already defined as (basically) <code>my-plugins/</code>. But this line just says "if glob is callable, then go through the directory for all underscore plugins". What happens if there <strong>are</strong> no plugins there? This would return false, maybe, instead of an array?</p> <p>And, is there a good reason NOT to include a blank directory for <code>my-templates</code> and <code>my-plugins</code>? At least then people would know where to put stuff. I mean, what IS the reason? WordPress comes with <code>wp-content/themes/</code> and <code>wp-content/plugins/</code> directories, and by default, two themes and two plugins. That eliminates the possibility of something missing. Of course, people could delete those, but right off the bat, they wouldn't and things would just <strong>work</strong> when they started out.</p> <p>At the very least, I think this should be fixed to have a conditional looking for underscore plugins before looping through them (i.e. if there are none, you can't loop through them.)</p> <p>Maybe someone with a better read on it can explain to me exactly what's happening. </p> http://bbpress.org/forums/topic/installation-problem-cannot-modify-header-information#post-13034 Sun, 06 Jan 2008 01:27:53 +0000 fel64 13034@http://bbpress.org/forums/ <p>Can you create the my-plugins directory in your root folder? I assume it isn't there, that's the only reason I can see for glob() to return false rather than an array. </p> http://bbpress.org/forums/topic/installation-problem-cannot-modify-header-information#post-13032 Sun, 06 Jan 2008 01:04:22 +0000 blue007 13032@http://bbpress.org/forums/ <p>Hi Guys,</p> <p>I´ve got a problemrunning the installation properly.
