   hi there.
   I know, wpmu is not supported but maybe you can still help me out.
   unfortunately I might have an imcompativle plugin, as this plugin ,breaks the wp-signup.php page within wpmu. it only loads a blank page if this plugin is active, the sourcecode ends with:

   <!-- all in one seo pack 1.4.7 ob_start_detected [-1,-1] -->

   I have checked the code of your plugin a little, and if I understand this right, it stops because it detects possbile problems with other plugins.
   how could I debug this problem? I'd like to find out which plugin it conflicts with...

   if possible without deactivating all plugins one by one :-(

   "how to debug" - deactivate all plugins and reactivate them one by one

   unfortunately, this doesn't work with wpmu. too many active plugins :-( and there is also a mu-plugins folder, where plugins are automatically activated.

   besides, a lot of plugins affect all blogs served by this instance, so I would break a lot of blogs, or have to put all blogs into maintenance mode.

   I was just looking for an easy way out, maybe by adding some code that prints out what conflict was detected?
   I mean this plugin detects a possible conflict? then halts its own execution and prints out <!-- all in one seo pack 1.4.7 ob_start_detected [-1,-1] --> instead?

   like I said, I know its not this plugins fault, I jsut need some help :-)

   yepp.

   2009-03-09 14:55:03 another plugin interfering?
   2009-03-09 14:55:03 detected output handler default output handler

   ok, can you help me understand that? I mean it must be something within another plugin that is detected, so what could I grep for?

   i.e. grep -R -i 'somethingtogrepfor' web/

   k, managed to try now. the above find was way too long...

   - renamed the plugins folder, no change, the wp-signup.php page still doesn't work.
   - moved all plugins out of the mu-plugins folder except for the maintenance plugin which I used to set the site into maintenance mode and the AIO plugin, signup page still broken.
   - changed the main blog theme, still broken :-(

   what further debugging can I do?
