I have the exact same problem on a client’s website.
I haven’t figured out a fix yet. I’m trying to get help from Optimizely, but no success yet. If anyone out there has a suggestion, please let me know. Thanks!
Hi @evsnm Is there any output in the console of the browser or any error message in the PHP log?
Hi @bradtaylorsf. I checked the browser console. Good idea. I found that the request sent when I pushed the “Create Experiment” button was returning a 403 response. That would explain the behavior. Here’s the response info:
status:403
message:"Your account plan does not allow conditional activation of experiments."
I switched to Immediate Activation Mode and now I’m able to create an experiment. Thank you for the tip!
Now I’m having problems getting the Variation Code to work. But that’s another story.
Marking this as resolved.
I had the same issues. In fact, even more severe: When I tried creating a headline experiment on a live website with significant traffic it broke everything leading to 504 Gateway Time-Outs…
What is Immediate Activation Mode and how can I use it?
Update:
My developer and host believe it was a server issue and it is just a coincidence the problems occured after trying to create a headline experiment. The plugin therefore most likely has no major issues.
I also found the Immediate Activation Mode. I had just assumed the plugin is as much plug-and-play as Optimizely itself; will read documentation from now on. 🙂
@buynai Good to hear it worked out for you.
For others who might read this post, the Activation Mode can be set at the bottom of the configuration tab on the Optimizely settings page. The help page is here.
