The customer complained today that they couldn’t change a page’s parts order, within a layout. I noticed this is actually on all servers. As soon as we try to move a part upwards/downwards the whole page freezes and the error below comes up in the browser’s console but nothing in backend logs. We’re using CS 4.0.4 on all servers.
Today we had the same issue on another project, using the same CS’s version. This time the problem seemed to be caused by a div between the data-portal-region and the each-component tags. Applying a th:remove tag or simply removing it did the trick then. I still gotta check if the original case’s html structure follows the same pattern.
