Sitemap not found on myopenhab

I’ve enabled myopenhab and I can see the events on the webinterface and I can also see my items throght the rest interface.
If I try to point to the sitemaps with the address I get the error:
org.openhab.ui.webapp.render.RenderException: Sitemap ‘casa’ could not be found
at org.openhab.ui.webapp.internal.servlet.WebAppServlet.service(
at org.eclipse.equinox.http.servlet.internal.ServletRegistration.service(

at javax.servlet.http.HttpServlet.service(
at org.eclipse.jetty.servlet.ServletHolder.handle(
at org.eclipse.jetty.servlet.ServletHandler.doHandle(

My sitemaps file start with:
sitemap casa label=“Casa”

What I’m doing wrong ?
Sitmap is showed pointing directing to my openhab internal address.

This might not help, but is the file named casa.sitemap, and are the file ownership and permissions such that the running openHAB server can read the file?

Is the sitemap in configurations/sitemaps/ and is the file casa.sitemap?

You were right… my sitemap file was named default.sitemap and not casa.sitemap.
Renaming the file was the solution.

Now I can see my sitemaps throght myopenhab but some time I get error 504 from the server, but thats another problem.
