Buddypress causing blank page with WordPress mu

I have installed WordPress mu and the install seems to be working fine. Once I add in the files for Buddypress, I get a blank screen. If I change the name of the mu-plugins directory (so that WPMU doesn’t recognize it) I can get see the WPMU site.

I have already changed the permissions (CSS, JS, themes) to 755, so I don’t think that’s the problem

Does anyone have any idea how to fix this? There is some sort of bug in Buddypress.

Thanks in advance for your help.

Please check your logs, there is no such thing as a blank screen. You can also turn on error reporting in PHP. Once you know what’s wrong, it’s usually simple to diagnose.

When I type my domain, nothing comes up as long as the mu-plugins directory is there. Once I delete it, I can see the WordPress blog (but then I don’t have the buddypress stuff and themes). I don’t know how to check the logs or how to turn on error reporting in Php

Did you check the permissions of the actual mu-plugins folder? Is the /mu-plugins folder in /wp-content?

I did check the mu-plugins folder (it’s at 755) and it’s in /wp-content.

Apparently this is happening to others, but no one has resolved it: https://buddypress.org/forums/topic.php?id=404

If you can’t check your logs or turn on error reporting then fixing this will be like finding a needle in a haystack.

I’ve checked with my service provider to see what they can tell me. As I mentioned before, others are experiencing this and there hasn’t been a satisfactory response yet.

I have checked all my permissions, and my WPMU install is fine. It’s just the buddypress that isn’t working properly.

@jfcarter Andy has told you that you need to provide the error that you are getting. Check your apache error logs and tell us what the error you have. It could be many different things and is not a widespread issue, so we need to know the error. You haven’t had a satisfactory response yet because you haven’t given any information to provide such a response.

@Trent, there is no error on the screen–it is totally blank.

This is the first anyone has asked for Apache logs (which I’ve requested from my webhost).

I only posted my question early this morning; when I said the response wasn’t satisfactory, I was referring to the other post which was never answered (and which may have helped me).

P.S. I had buddypress working at first, but deleted the blog by mistake. So I removed all the files from my server and reinstalled them and now they aren’t working (but WordPress MU is working fine). Does this help?

I’ve gotten the php log files (still waiting on apache), but don’t know what to look for specifically. Any help would be appreciated.

Did you wipe your database? The first 20 lines of your logs should be enough. Make sure you wipe anything sensitive.

Just to add, they will be the ones that say FATAL ERROR as well

Thanks, guys. Believe it or not there aren’t any errors in the log they provided. I’ve asked them to escalate a ticket to see if there are other logs, since I’m on a shared hosting plan.

Be careful on a shared host. WPMU shouldn’t really be run on anything less than a VPS. You might want to check your PHP logs.

Thanks. So far, wordpress mu is working beautifully. It’s when I try to add in the buddypress plugin that everything goes wrong.

Here’s the Php error that I’m getting:

Fatal error: Call to undefined function wp_get_current_user() in /html/wp-includes/capabilities.php on line 920

Any ideas?

Something is very wrong with your installation if you’re getting that error. That is a core WordPress function.

That sounds ominous. I googled the phrase and found several forums (with WPMU) where people reported the same problem and gave some fixes. No one seemed to think it was that big of a deal.

As for me, my WPMU works fine until I add the buddypress plugin; then it stops working.

Anyone have any solutions?

I found this post and it helped (https://mu.wordpress.org/forums/topic.php?id=7393)

In file wp-includes/capabilities.php add on line 2:

require_once(‘pluggable.php’);

Worked PERFECTLY!
