URL of experiment: [stroop\_3 [PsychoPy]](https://run.pavlovia.org/mlwell/stroop-demo/html)

Description of the problem: My experiment works perfectly on chrome but when i tried using it on safari it shows the following error

 ![safari error](https://us1.discourse-cdn.com/flex002/uploads/psychopy/original/3X/9/3/93d5730777c48e88cabcadbab525b2828fc60f0f.jpeg)

i checked [Wav file issue in Safari](https://discourse.psychopy.org/t/wav-file-issue-in-safari/17433)  
solved by @apitiot but it seems like the issue was solved by upgrading the psychopy version but i am using the 2020.2.10 and doesnt seems to help.

Thanks

I believe isn’t a copyright issue.

I use a both component to use wav or ogg locally and mp3 online.

How have you tried to tell PsychoPy to use wav locally and mp3 online?

Let’s say you have a column in Excel called SoundName

You could have SoundFile=SoundName+’.wav’ in Python and SoundFile=SoundName+”.mp3”; in JavaScript.

You’d probably then need to add the mp3 files as resources in the online tab of the Experiment Resources

thank you!  
I actually got another tip from @sotiri and changed the index.html in line 27 to  
script type=“text/javascript” src=“[https://cdnjs.cloudflare.com/ajax/libs/howler/2.2.1/howler.min.js](https://cdnjs.cloudflare.com/ajax/libs/howler/2.2.1/howler.min.js)”\>

instead of  
script type=“text/javascript” src=“[https://cdnjs.cloudflare.com/ajax/libs/howler/2.1.1/howler.min.js](https://cdnjs.cloudflare.com/ajax/libs/howler/2.1.1/howler.min.js)”\>  
and my wav files work now on safari 🙂
