We’re having the same issue, but we double checked that our URL is correct. We followed the directions here on our Dreamhost server, but when we actually tried running our experiment it says preloading for a long time and then an empty box appeared where our image should be. Here’s the demo experiment, where we tried replacing the logo with an image from our server. https://expt.pcibex.net/ibexexps/backColor/backColor/experiment.html
Any ideas on what’s going on? Appreciate the help!
Did you try with another browser and/or in incognito mode? I do see your own logo, no preloading time at all, so I suspect your browser is using an old version of the experiment in the cache
Thanks – it does work in incognito and in browsers it hasn’t been opened in before. However, it still won’t work in the original browser on the original computer even after completely closing and a day later. Is there any way to rectify that, maybe via Penn Controller itself?
The problem has more to do with how your browser handles cache than with PennController itself. Take a look to this page for how to perform a hard refresh—if the directions there don’t work, maybe consider clearing the cache for expt.pcibex.net entirely
