After MapEdit, I use MapBrowser and I see the words  "Loading 
map.......please wait", then I have the following error msg:

DrawMap: MapServer OGR Error: Open failed for OGR connection 
`Tbl_maplab.ovf'. File not found or unsupported format. in 
/maplab/common/wrapper/drawmap.php
DrawMap: MapServer Image Error: Failed to draw layer named 'Tbl_maplab'. 
in /maplab/common/wrapper/drawmap.php
DrawMap: MapServer OGR Error: Open failed for OGR connection
