got (maybe the same?) prob.
Using a pi2 with newest jessie, oc 4.4 wr-plugin and climatology plugin. Using the ready-build packages from the ppa.
When starting the wr-plugin I get an error message like (in short words) "no climatology data" but before starting wr I activate the climatology plugin
and I can see the climatology data on the screen
Trying to copy the data Folder to an other place but this does not solve the prob.
In the config-window the climatology-button is greyed out.
Using the grib optin produce an error "incompatible grid data"
