History

#1 Updated by Stefan Overkamp about 2 years ago

Same with https://www.wms.nrw.de/geobasis/wms_nw_dop.

The wms protocol window shows "...&STYLES&FORMAT=..." instead of "...&STYLES=&FORMAT=..."
Seems the "=" character is missing in QGIS 3.4 if no default style is assigned.
Choosing the default layer (ID 4 in wms_nw_dop) displays the wms image.
