Popups Openlayers showing on some layers, not on others

Question

I am having problems with my popups. On two layers they are showing (wfsLayer and wfsLayer1), on the other layer they aren't (wfsLayerBasic). wfsLayerBasic are new points which have been saved into my database with wfs-t. My hover function works, the features lighten up when hovering but no popup is shown. Can someone help me with this problem? I just don't get this, the code is identical..not even a emptry popup is showing.
