What does it mean when Google Analytics says "An Error Occurred"?
When this happens, you'll often see the message "An Error Occurred" displayed on all of your Google Analytics integrations and widgets across every campaign.
This typically results from having an ad blocker installed on your computer. Most often this will be a browser based ad blocker, but can sometimes be an ad blocker that's integrated into your antivirus utility.
The solution is to either turn off your ad blocker completely or to white list our site if your ad blocker offers that option. Once you do so, you may need to do a hard refresh on your browser in order to see the change take effect.
