I have a working WordPress 3.0.1 installation. I manually installed BuddyPress 1.2.6 and activated the plugin. I have edited permalinks and lighttpd.conf for url rewriting. I get an index offset invalid error in line 85 of bp-core-catchuri.php. $bp_uri is an empty array in my case, as I have installed wp in a sub-directory of my main domain.
From this point onwards, no Buddypress feature works.
I re-installed my whole setup and used 1.3-bleeding version of Buddypress. With this I get a different error:
[30-Oct-2010 21:26:23] WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id = 1' at line 1 for query SELECT * FROM WHERE id = 1 made by require_once, require_once, require_once, do_action, call_user_func_array, bp_loaded, do_action, call_user_func_array, bp_setup_globals, do_action, call_user_func_array, bp_core_setup_globals, bp_core_get_user_displayname, xprofile_set_field_data, BP_XProfile_Field->bp_xprofile_field, BP_XProfile_Field->populate
Please help! Thanks.
