How did you upgrade the kooboo cms.
The regularly step is:
1. Unzip the Kooboo_CMS.zip into to a new folder.
2. Copy the old "Cms_Data" into the new Kooboo CMS folder.
3. If you are using the SQLServer,Mysql,MongoDB provider, please also deploy the provider assembly into the BIN of new Kooboo CMS folder, then copy the folder SQLServer.config/Mysql.config/MongoDB.config into the BIN folder.
