[Mapbender-users] Mapbender3 Geoserver layers not visible

[Schepers, Benjamin]

Hi Mike,

Your problems could be caused by misconfigured owsproxy. Maybe this there's also bug with owsproxy and php7? Maybe you can first try not to use any proxy-functions, until you properly configured this? 
Moreover I'm not sure, whether you would need any proxy settings, because all your stuff (MB3, services, etc.) seems to come from the same machine/domain.

So I'd try this:
Have you unchecked the Proxy-checkbox for the specific layer(s)? This could be done going to the application -> layerset -> edit layer-instance. If proxy for this layer-instance is unchecked, also have a look to the "vendor specific" section at the  same tab (it seems to me, that your error message lead to vendor-specific). If there are some vendor specific settings configured by you, delete/deactivate them, normally you would not need to pass vendor parameters to the wms-server or if vendor-specific is really needed, at least uncheck hidden (which would also make MB3 use the proxy-module).

If you need to configure proxy, this should help you:
