Hi Hadis,
Google satellite data are available for zooms between 0 and 7 (xmax and ymax
are 127). To avoid the pink tiles, you should limit the maximum scale factor
(or Min Scale for layer config) to display your layer.

Pierre
Thank you for your response. By replacing that with
<https://mt0.google.com/vt/lyrs=m&hl=en&x=$%7bx%7d&y=$%7by%7d&z=$%7bz%7d>
https://mt0.google.com/vt/lyrs=m&hl=en&x=${x}&y=${y}&z=${z} still I get the
error and I see the pink background with no map. However, by using the example
tile and specifying <https://mt0.google.com/vt/lyrs=s&x=1&y=1&z=2> x=1&y=1&z=2
I see the tiles (multiple similar tiles in the fusion) showing somewhere in the
world. And when I use the Theme widget it classifies the layer and the tiles
are still there. It looks like I am getting close to the right answers and have
the background map with the themed layer.
My question is how to get the right tile location and scale that is matched my
layer's bounding box.
Thank you
Hadis

Objet : [mapguide-users] fusion theme -No access control allow origin error
Hi,
I am using MG version 3.1.2 on IIS. On the fusion, when I use the Theme widget
I get the themed layers and it's added to the legend but the base map of
Openstreet doesn't load and the cursor spins forever. By Looking at the errors
in the console I see the 100 errors of "access to the image at
<https://c.tile.openstreetmap.org/5.379310131539869/13/13.png>
https://c.tile.openstreetmap.org/5.379310131539869/13/13.png from the origin my
website address has been blocked by CORS policy: No
'Access-Control-Allow-Origin' header is present on the requested resource" and
the same error for <https://b.tile> https://b.tile and a.tile.
Just letting you know I tried adding and removing basemaps even Generic XYZs
still get the same results and error.
Removing the openstreet map and with Generic XYZ for google street I get the
error as follows:
GET <https://mt1.google.com/vt/lyrs=s&x=262143&y=262143&z=19>
https://mt1.google.com/vt/lyrs=s&x=262143&y=262143&z=19 404
