Re: Updated using automatic update now site is hosed
Before updating buddypress you should always deactivate any plugins that require BP in order to work.
At this point the only solution I have would be to go in through FTP and remove any offending BP plugins from wpcontent/plugins. You don’t have to delete them necessarily, just get them out of the plugins folder and refresh your site. Copy them into a folder on your desktop so you can re-establish your plugins after you have finished the upgrade.
Once you have the upgraded version running, then start to rebuild your plugins by pulling them back in to the plugins folder (again via FTP), then reactivate them (ensuring that BP is active before you enable BP specific plugins) one by one in the plugins menu under admin until you are back in business.
