Re: Groups wont let me edit
That message “Are you sure you want to do this? Please try again” is a nonce failure message. Did you upgrade and not upgrade the bp themes? All bp code is now ‘nonce security’ aware. If your themes don’t send these ‘nonce’ values to bp everything comes to a screeching halt.
For example:
<p><input type="submit" value="<?php _e( 'Save Changes', 'buddypress' ) ?> »" id="save" name="save" /></p>
<?php wp_nonce_field( 'groups_edit_group_details' ) ?>
That’s taken from the edit group details form. wp_nonce_field() creates a little hidden field with an access key for ‘groups_edit_group_details’ that gets compared in to a similar ‘nonce’ value generated in the actual function that does the validation and saving of group details. If they don’t match, the security check fails with that cryptic message from wpmu.
