DatafileManager: Error fetching datafile: Request error

Problem

I'm using Optimizely to code-gate my new website. But the allowed accounts aren't getting through. The first Firefox console error is

[OPTIMIZELY] - ERROR <timestamp> DatafileManager: Error fetching datafile: Request error

How do I fix this error and fetch the data file?

Solution

  • DatafileManager: Error fetching datafile: Request error

    One of the network failures helped me out. The GET request for cdn.optimizely.com had "Blocked by AdBlocker Ultimate" in the Transferred column.

    I turned off AdBlocker Ultimate for this site.
