Hi
I'm sorry, but do you use correct call.
Plugin it is plugin for component, it uses it's data.
Ie
56 - have you got this map, ie map with ID=56
Look at map list, the first column - it is ID
wiki.zhuk.cc/index.php?title=Zh_BaiduMap...ription#Creating_Map
The second
wiki.zhuk.cc/index.php?title=Zh_BaiduMap_Plugin#Show_Map
This is parameter position for plugin call by map ID
Compare my request
{zhbaidumap:MMM;Zoom;MapType;Width;Height}
and your values
{zhbaidumap:56;8;23.743193;90.388281;400}
It means
Map ID = 56
Zoom = 8
Map Type = 23.743193 - ERROR
Width = 90.388281 - ERROR
Height = 400
Plugin call doesn't support passing coordinates (Latitude, longitude)
You design your map in component (in administration: creating maps, placemarks...)
After that you can only show your data - by menu (component call), or in an article - by plugin call.
You enter your location - coordinates, in placemark details
