Custom table's data hangs on the loading screen after saving any changes. This is happening on some of tables and it seems that the majority of records are saved, however I have noticed a couple that didn't save within some custom table until reapplying the change!
I was wondering what can cause the issue.
I have found the issue using browser's developer tools.
Clicking save button was creating
Mixed Content: The page at 'https://address' was loaded over HTTPS, but requested an insecure form action 'http://address'. This request has been blocked; the content must be served over HTTPS. JS error on the browser and browser was blocking the content. However, the form action was not pointing to absolute URL address.
As the server SSL config was fine, therefore, there was not any other way than changing core CustomTableForm.ascx.cs Kentico file. Although it is not recommended. The problem solved by developing RedirectUrlAfterSave property of customTableFormobject to make sure it will redirect correct protocol instead of Absolute URL
Hope it will help you guys.
