I use the default settings for myblog (registered level for posting and publishing); tried to set the level to author but the horrible message don't disappear. I remember to have seen this message with myblog uninstalled during upgrade process (and before the installation of FB with GroupJive). The error message is not a BIG problem but VERY irritating. I have the error since the begin I think. Maybe a problem with CB installation?
nope its not a bad CB install.. it is a permissions problem,,, you have public viewing of cb profiles with plugins that at min require registered membership to view,, obviously you will get this message.
again, you need to go through each piece of content and all components, troubleshoot them all and then you will have your answer as to which is causing your message to display.
given your comment >>>I use the default settings for myblog (registered level for posting and publishing); <<< right there may be the problem.. if My Blog is set min to registered (by default) but your allowing public view of the profile... there is going to be a permissions problem.. public can not view registered resources ( its that way for obvious reasons)
