Re: Fatal error after upgrading to BP 1.1.2
I ran into this exact same error:
Fatal error: Cannot redeclare bp_activity_install() (previously declared in …/wp-content/plugins/buddypress/bp-activity.php:19) in …/wp-content/plugins/buddypress/bp-activity.php on line 52
If you have a failed upgrade, I recommend reverting to a “clean” backup of your files and database from before you upgraded Buddypress or attempted reactivation.
Here’s what I did to successfully upgrade from BP 1.0.3 to 1.1.2:
1. Switch to a non-BP theme, i.e. WordPress mu Homepage 1.6
2. Deactivate ALL plugins (you’d probably be okay by deactivating only BP-dependent plugins but I did this just to be safe)
3. Delete Buddypress plugin files (/wp-content/plugins/buddypress) via wp-admin or FTP, either is fine
4. Download the Buddypress 1.1.2 zip and upload the new files to your plugins folder
5. Activate Buddypress plugin in wp-admin
I can’t comment on what changes you have done to your install or what plugins you’re running but I had similar problems with the upgrade and the steps above allowed me to successfully upgrade BP.
