The Sidekick does not show up when page is opened in authoring.
One of the possible reasons for this could be that the sidekick is not able to load one of the components added to the paragraph system in design mode. This could be due to a problem with the component.
You can also try to delete components loaded by the sidekick one by one in CRX to see which one might be causing the . To do this do the following -
/etc/designs/[your application name]("your application name" is the name of your application's design configuration node). The structure in
/etc/designsis parallel to your templates' content structure. For example,
/etc/designs/geometrixx/jcr:content/homepage/paris a paragraph system in Geometrixx's homepage template. The content structure under
/etc/designseffectively parallels your page content structure like this like this-
/etc/designs/[your application name]/jcr:content/[template name]/[parsys node name].
