Tileset Error (Layers)

[AlexanderK]

Someone logged onto my Server and couldn't see the Tileset. He made a screenshot for me.

It seems like only the uppermost layer is displayed.

So is that a problem on my or on his side? I would greatly appreciate if someone logged onto my server(Dev AlexanderK) and told me if they had the same problem, because everything diplays just fine to me.

If it is a problem on my side,what can I do? Should I just stop using layers all together? Or limit myself to a number of layers? I use 3 right now.
