Creating fishnet grid Shapefile in QGIS?
Look at the Processing Toolbox and you may choose many algorithms without the need of a plugin
You don't need a plugin, just use a geoalgorithm from the toolbox:
Vector > Research Tools > Create Grid...
In QGIS 2.10 this is called 'Create Graticule'
Vector grid creation has been incorporated in QGIS for a long time:
Vector -> Research Tools -> Vector Grid
Note that the default grid spacing of 0.0001000000
units of the layer CRS is too small in most cases.
You might want to use Vector -> Geometry Tools -> Densify Geometries
afterwards if you need to reproject the grid to another CRS where the lines should appear bended.
