Force parameter is not working!
Looks like you're using force query parameter, here. I just tried your URL which loads fine, but when I check the Optimizely object using the browser's console (see Optimizely's article on this, here), it shows that you have no activeExperiments. Then, insteead of checking activeExperiments I checked:
This showed me you have 2 experiments in your project, 3444370380 and 3524080847. Neither of these experiment IDs match the experiment you've provided in your URL. So it looks like this experiment isn't part of the project.
Here are some things to check:
- The snippet on your page is http://cdn.optimizely.com/js/3471290170.js, so check your experiment is in this project (id 3471290170) and not another. If it's in another, move it to this project, or change the snippet on your page
- Check whether your project hasn't been excluding draft experiments, or simliar privacy settings that mean the snippet can't access the experiment at the moment, here.
I hope that helps you get to the bottom of this!
