Hello, I have a problem, and it's the first time it's happened to me. In the pages created with SP Page Builder and included in the quickstart package, the various elements on the page (slideshow, heading, etc.) are blank, even though their content is visible on the front end. For example, on the home page, there's a slideshow with some text. If I go to the back end of the page and click on the icon to edit the content, the "General" tag is completely blank. How can I fix this? Thanks!
