Hi Harald
This can have many reasons. The most common are:
- There can be a firewall issue where the required ports - starting at 9000 - are blocked (lately I've even seen a server with an outgoing blocking for some ports, including those needed here).
- The value for "ExternalHostName" in your OpenSimulator, in the /bin/Regions/Regions.ini should be in most cases "SYSTEMIP". But if your OpenSim runs in some DynDNS enviroment, the FQDN of this DynDNS should be entered...
Sometimes, you get more information if you take the image url from the gridmaps source code and enter it in a seperate browser window/tab.
E.g. taking the first image from my demogrid region up left (RiverSide), it shows in the source code:
<img id="mapimage_0" name="mapimage_0" src="
/components/com_opensim/assets/regionimage.php?uuid=e14e6a99540f4bc883efbc53492a6532&mapserver=80.190.246.228&mapport=9000&scale=256&info=no" alt="RiverSide" title="RiverSide" border="1" height="128" width="128">
... adding the path of Joomlas base, I get:
www.foto50.com/components/com_opensim/as...246.228&mapport=9000
Not always, but in some cases, there is displayed some information, in case something goes wrong with the image (Note: MSIE is here more informative than FF).
If this is no help, you also still can at least have a check, if your OpenSimulator creates the images correct. You can build the direct url from the above in the way:
http://{mapserver}:{port}/index.php?method=regionImage{uuid}
In my case:
80.190.246.228:9000/index.php?method=reg...4bc883efbc53492a6532
If this generates the map image for you, at least the config of OpenSim and the firewall of it's server should be correct.
In that case, more intensive bug hunting would be necessary. But I hope, the above already leads us to the error.
