Troubleshooting: Unable to Open App Settings Panel
Normally, you can access the settings for your apps by clicking the app in the editor and then clicking Settings.
If the Settings Panel does not open, it may be because it is blocked by browser settings or by ad blocking browser extensions / add-ons, such as AdBlock.
To solve the problem, check the following:
Have a look if popups are blocked by your browser:
In your browser settings, check to see if any browser extensions / add-ons that block popups are enabled.
Another way to test if ads are blocked on your computer, is to open your browser window in incognito mode. If you are able to see ads, disable your browser extensions and Internet monitoring software applications one at a time. This may help you determine which ones are blocking your ads.
