When trying to view OSM tiles using the external storage example of OpenLayers, I keep getting black tiles when I zoom in and out.

I don't know what the issue is but every time I zoom in/out there are black tiles that appear.

Please help me.

Which OSM server are you using? Any error messages? Which version(s) of arcmap? –  BradHards Jan 7 '13 at 8:44
Sorry Bro...OpenLayers-2.12 ...I am using the Offline Storage Example ..and I get no error .. :( –  Fhd.ashraf Jan 7 '13 at 8:48
So you are not using arcmap? Are you using openlayers.org/dev/examples/offline-storage.html or a local instance? –  BradHards Jan 7 '13 at 8:55
Local Instance and when i upload it on my server... –  Fhd.ashraf Jan 7 '13 at 8:59
What do you see in your server logs? Does it work correctly on the openlayers example site I linked to? –  BradHards Jan 7 '13 at 9:01
