The user is upgrading DNN version [7.3.4] to a newer version[9.1.1]; however in the older version where DNN modules had a class Normal added to HTML, modules are not getting added in the newer version.
Environment: DNN version [7.3.4]-[9.1.1]
Root Cause: After the change at DNN version 7, the Normal class is no longer added to every module container.
- Use DNNModuleContent class instead, which is still part of every module and it sits right outside the module content which used to have the Normal class.
Confirmation: The normal class will be added to every module.
