Hi,
Thanks for the quick reply. I have checked both of your suggestions. license still not working at all.
I unzip the two license files(smithcartlicense1,smithcartlicense.key) on my PC, and used FTP upload both files to the dnn installation root folder which is web.config file resided.
Also, have checked with our hosting side, recycle the IIS already.
What is wrong with the processing or anything wrong with the license?
