Re: Publish services: status bars have disappeared!

Would suggest you to reset Lightroom Preferences.

Before doing that, make sure you know the location of your catalog. If not, go to Lightroom settings under Lightroom and check the location under General tab.

Then, to reset Lightroom Preferences :

1. Quit Lightroom.
2. Navigate to the preferences file:
   • Mac : /Users/[user name]/Library/Preferences/com.adobe.Lightroom6.plist
   • Windows : C:\Users\[user name]\AppData\Roaming\Adobe\Lightroom\Preferences\Lightroom 5 Preferences.agprefs
     
3. Move the .plist/.agprefs file to desktop.

* The user Library file is hidden by default on Mac. For temporary access to the user Library file, press Option and choose Go > Library in the Finder.

then, open Lightroom catalog again and check under Publish collections if you are able to see those headers.

Let us know if that helps.
