Millisecond Forums

Hello, 

I am trying to run a script on the web version (https://mili2nd.eu/kn2b), but I get the errors:
"Unable to load the picture 'https://scripts.millisecond.eu/jurquhart/perspective_taking_yajing/female avatar+left+barrier+45°+上+mirror-inverted.png'. Network Error: Error transferring: 403"
for most of the stimuli. 
The script first asks to choose a language, then when one is selected a new script is loaded and then I get the error. The script runs fine in the lab version. I checked that all the stimuli has been uploaded and it's all there.
Any help much appreciated,
Thanks,
Katrina
