I'm working on a custom skin for the 7.2.2 version of DNN community. From some time (it also happens with earlier versions) the HTML module do not save changes. I insert the HTML module in the content panel and then I introduce the content (text or images), but after making the necessary changes when I select the button of update the popup window that contains the editor do not closes, and if I force the closure with the cross button on the top right does not get saved content. What can be the cause of this issue? Thanks for the reply.
