I installed buddypress but I am continuously seeing 404 errors and in apache logs it says this. However I can “Activity” directory somewhere inside wp_plugin. What can I do to make these pages available?

What’s in your .htaccess file?

[mwp]

I don’t have .htaccess file

[@mercime]

You need one or else you can’t use BuddyPress.

https://codex.wordpress.org/Installing_WordPress

It doesn;t really say what should be there in .htaccess file. Can you point me to some other doc that gives that info.

BTW: I am able to get the main home page but then none of the links work. They give that 404 error.

Deactivate BuddyPress and BP plugins. Run Settings > Permalinks and choose permalink other than default. https://codex.wordpress.org/Using_Permalinks#Where.27s_my_.htaccess_file.3F and next topic below that is content of htaccess for single WP installation

Resolve WP installation before activating BuddyPress. Also if you plan to allow blogs for your users, create a network i.e. go multisite and resolve any issues before activating BuddyPress.

I had to reinstall wordpress. I got tons of errors when I try to add buddypress plugin in the latest 3.1 wordpress:

These are not errors, but debug notices.

Most of these debug notices have been fixed in the forthcoming version of BuddyPress.

Do you have WP_DEBUG defined?

[mwp]

Yes I have. But what I see is that I start getting 404 as soon as I install buddypress. And it doesn’t let me login once I logout. I then keep getting “You have already installed wordpress please login”. I had to re-instlal wordpress and struggling with getting buddypress up and running. I even tried updating .htaccess file as suggested earlier but that didn’t help.

What is wordpress doing with mod_rewrite? How can I debug if it’s being used or not?

[r-a-y]

Did you enable pretty permalinks like mercime suggested? Are you using the latest version of BP?

Did you install WordPress in a subdirectory with these instructions?
https://codex.wordpress.org/Giving_WordPress_Its_Own_Directory

If so, there are bugs with BP 1.2.8 relating to subdirectory installs.

Please read this thread to resolve the login/logout issue for now:

Yesterday I re-installed wordpress 3.1. I go to plugin and search for buddypress and then install it from there, I am assuming this gets me the latest version. At that time I did enable permalink.

What I do is I mv wordpress /var/www/html/.

How can I tell if re-write is working or debug this problem.

[r-a-y]

Yes, using the admin panel to install BuddyPress will always download the latest, stable release.

Don’t move the wordpress directory! If you need to reinstall WordPress in the root directory, do it from scratch!
