SSL & dhtmlTree loadXML


I have a problem with dhtmlTree on secure connections (SSL, https).
I appeal to the loadXML function, but this does not work well and the tree looks with ‘???’
Any suggestions?
Attached picture.

This looks as problem with data encoding
Tree itself works fine other ssl

Thanks for the reply.
I have discarded the data coding problem. The problem only arises when loading Arboló the loadXML method. You can not see the images either.
Thanks again.

If issue still occurs - please provide any kind of sample or demo link where issue can be checked
