Re: wordpress mu installation with buddypress
A few things to consider when seeing….(white screen)
First, if you are creating sub domains for each individual blog make sure the blogs are being confirmed through the submitted email during registration. you will see a white screen for every blog not confirmed.
Second, make sure all permissions are enabled in your dashboard, this too causes white screens for different blogs.
Third, make sure you deleted the bp themes in from the /mu-content/ root and that they are installed through the /mu-plugins/ not /plugins/
Fourth, a lot bp plugins take some sort of config to work correctly, sucks I know but true so I would definitely follow DJ Puals advice and deactivate all plugins while you try my suggestions.
You might be thinking that it’s a lot more difficult than that but Sometimes it’s as simple as that.
