Anything in the server error log?
Are you using any other plugins beside BP? Have you already started a custom theme using the new method in BP 1.7 perhaps?
Have the solution — the code to implement the BP_Legacy class in buddypress-functions.php had changed between beta and full release.
I needed to update the buddypress-functions.php file in our theme to match these changes.
@r-a-y: thanks for getting back to me. Yes, this is a considerable build based on the new theming approach — it’s been about 4 months in development (with a number of devs involved). We’d seen it through a number of alpha / betas of 1.7, so was a bit of a shock when the WSOD appeared! Anyway, that problem sorted now.
Yes, it did 🙂
Which is why I asked if you started a custom theme using the new method. Glad you figured it out!
@r-a-y — looks like your reply and my edit with thanks crossed!
Cool! The change was made for the better as custom themes shouldn’t need to add all that BP conditional logic in their custom buddypress-functions.php file.
If possible, please share a link to the new site once it’s launched!
