Cannot run simple experiment on Pavlovia (returns 404 not found error)

I have an experiment that runs locally, but whenever I try to run it on Pavlovia, it only returns a 404 File Not Found error. The same thing happens for all experiments, even experiments that I downloaded and have worked for others (Error 404 - previous options did not work - #9 by wakecarter). My hypothesis is that there’s a browser setting that needs to be changed, but I’m unsure what that would be. I have also tried running it on different computers, which returned the same set of errors. I’m running this on a Mac (Version 12.3.1) with PsychoPy (Version 2022.2.5). Any thoughts would be greatly appreciated.
