On SharePoint online I just finished creating an intranet and each page has a script-editor web app with a jquery script that's used to style summary link controls on the page. The script is also designed to make each group in the summary link control collapsible. The issue is that owners with full access to the site can see the jquery working since they can collapse the summary link groups whereas members and visitors cannot. They can see the summary link control styled but they cannot collapse the individual groups. I think this may be permissions related but I am uncertain. Any advice on the matter would be much appreciated.
Check if "each" page is checked-in/published. Also, if you referenced any external files in script editor wp ... that files should be checked-in/published as well. Let us know if this helped.
