Due to unknown reason, I cannot connect to official plugin service in these days. Alternatively, I downloaded the zip file of QuickMapService and unziped it to the directory
C:\Program Files\QGIS 2.18\apps\qgis\python\plugins
My QGIS version is 2.18.3 and I have enabled the plugin in the plugin manager.
However, the manager show me the error message like
Coordinate Capture
Capture mouse coordinates in different CRS
Category: Vector
Installed version: Version 0.1 (in C:/PROGRA~1/QGIS2~1.18/apps/qgis/plugins/coordinatecaptureplugin.dll)
I'm not sure it's due to the plugin itself (unlikely!) or the way I install the plugin (wrong directory?). Any suggestion?
