[Mapserver-users] View problem with overlaying WMS layers

[Tommer]

I'm using MapServer 4.02 and I have a problem with viewing of WMS connected layers from other servers. When only one WMS layer is on, everything is OK. But when I turn on more layers, only one is shown. Problem is not with transparency, all layers are transparent, because I can see local layers bellow, when only one remote layer is turned on. Sometimes, when I turn several times on and off one layer and the other one is on, this two layers are shown correctly. Sometimes the original layer turnes to grayscale, however. And sometimes is shown nothing at all. Is it problem on our side in the mapfile or in the MapServer? Or would it be problem with remote WMS connected server? Thank you for a help. Tom Mercl

Here is part of my map file.
