Hi Sebastian
Well, i have imported a version 4.9.4 Language pack via Install Extension and translated the missing strings to Danish, every time choosing System.
In Admin->Language i choose Create Language Pack, selects Danish, selects Full, Resource pack name unchanged and click Create.
I have serched for any language pack files on the server, there is none in folders that DNN know.
Is it still in the folder \Portals\_default they are created? ("Network service" has full access, so its not a security problem)
What else can i tell you.....hmm.
Oh, yes, there is a known problem with saving the \App_GlobalResources\GlobalResources.da-DK.resx file in DNN4.9.4, when i imported the resourcepack into DNN5.1.4 the error followed with. I had to delete the GlobalResources.da-DK.resx file and create a new one.
Hope this info helps :-)
