AEM 6.4 - No overlay in Edit or Design more
I'm updating an AEM application from 6.2 to 6.4. After the update, things are working normally. However, in edit mode and design mode, there is no overlay, hover states, or drag and drop areas. I can't edit anything, no components show up in the sidekick or the content tree, and I can't use design mode to update the settings for the page or parsys, because there is no overlay there either. Basically, there is no way for me to interact with the page via edit, design, or targeting mode. I'm wondering if anyone has any ideas as to what could be the cause. It's not even that I can't add a component to a parsys - the "drag components here" is not even there. Nothing highlights as I mouse over, etc.
- I am admin, so it's not permissions related
- The default design nodes look fine for these pages and components
- I tried creating design dialogs for the components, but those don' work either
- The components all show up under /libs/wcm/core/content/sites/components.html and they look fine
- All bundles are started
- The website works completely normally otherwise
Any ideas?
